AMEC has said its trading year-to-date is in line with expectations with good order book of £3.7 billion at the end of December 2011 and forward visibility.

AMEC is confident that this will support the double-digit underlying revenue growth in 2012.

The engineering services provider purchased £75 million of shares under £400 million share buyback programme.

"AMEC has performed in line with expectations in the first three months of the year. We continue to see healthy demand for our services and investment in our end markets - underpinned by the positive industry trends, particularly in the oil and gas and mining sectors. We are confident that this will support double-digit underlying revenue growth in 2012," said Samir Brikho, CEO while commenting on the results.

"The acquisitions made in 2011 are integrating well and the pipeline of further acquisition opportunities remains strong." Samir added.
