In a trading update in December Amec warned that it had reduced pre-tax profit expectations by £15m.
This week it posted a pre-tax profit of £105.2m and turnover of £4.3bn for the year ending 31 December.
Amec also announced that it had completed the acquisition of French construction group Spie but signalled its intention of selling Spie's regional contracting arm, Spie Batignolles. Chief executive Peter Mason said that with the Spie acquisition, Amec was established as the UK's premier international engineering services company.
He said: "Amec is well positioned in major markets. Contracts expected to be worth more than £1.5bn give us increased confidence of a return to organic growth in 2004."
