Board Changes

Costain Group PLC ("Costain" or the "Group") is pleased to announce that Steve Mogford and Amanda Fisher will be appointed to the Board on 1 November 2023 and 1 December 2023 respectively as independent non-executive directors. Steve and Amanda will be members of the Company's Audit, Nomination and Remuneration Committees.

Steve is an experienced executive and non-executive director with extensive expertise in water, defence and complex joint ventures. Steve was CEO of United Utilities Group PLC from 2011 until March 2023 and led significant growth during that period. During 30 years at BAE Systems plc, Steve held various senior positions before being appointed COO and a member of the board. Steve is Senior Independent Director of QinetiQ Group plc and was previously Senior Independent Director of G4S plc.

Amanda was CEO of Amey, the engineering and infrastructure company, from 2019 until 2022. With considerable expertise in transportation, infrastructure and defence, Amanda restructured the business, re-defining the strategy and improving contract risk and performance, leading to its successful sale in 2022. Prior to Amey, Amanda held two managing director positions at Balfour Beatty plc, improving their market share in key sectors, and held a senior management position at the construction firm, Alfred McAlpine. Amanda is an independent external Governor of the University of Plymouth.

As part of this change, Jacqueline de Rojas and Neil Crockett, non-executive directors, will step-down from the Board on 31 October 2023.

Kate Rock, Chair, said: "The Board is delighted to welcome Steve and Amanda to Costain. Both bring a wealth of experience in key markets, including energy, water, highways, and rail. They have driven improved profitability and increased market share, and I look forward to working with them to support the growth we expect in Costain's operating profit and margins.

"I would like to thank Jacqueline and Neil for their considerable contributions to Costain and guidance to the Board over the course of their tenures. Both have provided significant advice and insight, supporting the Group's strategy for growth."
