SFO investigation

In its circular to shareholders published on 23 May 2017 the company disclosed that the UK Serious Fraud Office (SFO) may well commence an investigation into Amec Foster Wheeler. The company confirms that today it has been informed by the SFO that it has now opened an investigation into Amec Foster Wheeler, predecessor companies and associated persons in respect of the

Foster Wheeler business. The investigation focuses on the past use of third parties and possible bribery and corruption and related offences.

Amec Foster Wheeler takes its obligation to conduct business ethically very seriously and has in place a robust global anti-bribery programme, including a detailed code of conduct and anti-bribery and corruption policies. Amec Foster Wheeler continues fully to co-operate with and assist the SFO.

Given the stage of this matter, it is not possible to estimate reliably what effect the outcome of it may have on Amec Foster Wheeler. However, the SFO's investigation is not expected to have an impact on the completion of the merger of Amec Foster Wheeler and John Wood Group, which is expected to take place in the fourth quarter of this year.
