ASX RELEASE

6 February 2012

MONADELPHOUS DIVESTS STAKE IN NORFOLK

Leading engineering group Monadelphous Group Limited (ASX:MND) (“Monadelphous”) today announced it sold its holding in Norfolk Group Limited (ASX:NFK) (“Norfolk”) of 22,210,268 shares, representing 13.98 per cent of issued capital, in an on-market transaction on Friday for a cash consideration of $24.4 million.

Monadelphous acquired the majority of its initial strategic interest in February 2009. Norfolk operates a broad suite of businesses providing services to the industrial and infrastructure sectors. The acquisition was part of Monadelphous’s diversification strategy to broaden exposure to non-resources markets.

Over recent years, Monadelphous has diversified its services to the infrastructure market and continues to develop its position in selected infrastructure segments. As a result, ownership in Norfolk was no longer considered strategic.

This transaction will result in a one-off pre-tax profit of $16.2 million, which will be realised in the financial results for the year ending 30 June 2012.

“We are pleased with the outcome of our investment in Norfolk. We have taken the opportunity to realise the strong return from our investment which will support the ongoing growth of our business, including the continued development of our infrastructure strategy,” Monadelphous Managing Director Rob Velletri said.
