Transaction in Own Shares

On 21 February 2012, AMEC plc ("the Company") announced that it intended to complete a £400 million share buyback programme within the next twelve months.

Today the Company announces that it has purchased 200,000 of its ordinary shares of 50p each at 1116.19 pence per share through Deutsche Bank AG. All of these shares will be held as Treasury shares and utilised, as normal practice, to satisfy the obligations of the Company's Savings Related Share Option Schemes. This purchase equates to approximately 0.06 per cent of AMEC's current issued share capital excluding Treasury shares prior to this purchase.

AMEC's total issued share capital is 337,965,871 shares. Following the purchase of these shares, AMEC plc holds 6,576,155 of its shares in Treasury and has 331,389,716 ordinary shares in issue excluding Treasury shares.

Cumulative purchases to date under the buyback programme amount to approximately £22.67 million.

Going forward, it is the Company's intention that the significant majority of the shares purchased under this programme will be cancelled.
