Interim Management Statement 14 November 2012

Group performance

Year-to-date trading continues to be in line with expectations.

Order intake remains good and includes a mix of new contract awards, scope changes to existing contracts and walk-in work providing good visibility for 2013 and beyond. The order book was £3.6 billion at 31 October (October 2011: £3.3 billion; June 2012: £3.7 billion).

Contract awards announced since 30 June include:

§ The detailed design contract for GDF SUEZ E&P Ltd's Cygnus gas field development, UK North Sea

§ A project management consultancy services contract for the remediation of Kuwait Oil Company's (KOC) oilfield properties damaged during the 1990-1991 Iraqi invasion of Kuwait

§ A contract to provide engineering and procurement services for the Balkan Minerals and Mining EAD (BMM) Krumovgrad gold project, Bulgaria

§ A five-year contract to provide project management support for the refurbishment of National Nuclear Laboratory's (NNL) active handling facility, UK

§ A three-year contract to provide waste treatment services to the Bohunice nuclear power plant, Slovakia

§ An engineering, procurement and construction (EPC) contract by International Power Canada for the Brockville solar project, a 10-megawatt (MW) solar photovoltaic plant, Canada.

Elsewhere, good progress continues to be made. Whilst mining activity is slowing, conventional oil and gas activity is strong, particularly in the North Sea and Gulf of Mexico where work continues on a number of major projects.

The average number of employees was 28,250 in the period January to October 2012.

Acquisition update

AMEC completed two acquisitions in the first half of the year; Serco's 600-person nuclear Technical Services (TS) business and Unidel, a 260-person energy, resources and infrastructure engineering and consultancy business in Australia. Integration of both acquisitions is on track.

Momentum continued in the second half of the year and, in September, AMEC agreed to acquire a 50 per cent stake in Kromav Engenharia Ltd (KROMAV), a privately owned Brazilian offshore oil and gas and marine engineering company. In October, the group formed a joint venture with Samsung Heavy Industries and Samsung Engineering to carry out the design engineering for fixed and floating offshore platforms, FPSOs and subsea pipelines for Samsung's future offshore oil and gas projects.

Financial position and net cash

The group remains in a strong financial position. Net cash at the end of October was £124 million (October 2011: £430 million; June 2012: £290 million) after share and acquisition-related outflows.

Outlook

Demand for AMEC's services continues to be good, despite on-going economic uncertainty. The group is on track to deliver double-digit underlying revenue growth for the full-year 2012 and continues to expect to deliver good growth in 2013.

AMEC is firmly focused on delivering revenue and EPS growth and maintaining margin discipline.

The balance sheet remains strong and provides a robust platform for further growth. The group continues to look at further acquisition opportunities.
