Interserve has appointed Mark Whiteling as chief financial officer as the contractor continues its turnaround operation.

Mark will join the company at the beginning of next month, having recently held a number of non-executive roles at firms including Hogg Robinson and Connect Group.

He will also take up a seat on the company’s Board.

Mark has considerable listed company experience having held deputy and interim chief executive and chief financial officer roles in Premier Farnell Plc prior to its take-over by Avnet, and finance director of communisis and group finance director of Tibbett and Britten.

Mark started his career with Coopers and Lybrand in New Zealand before moving to the USA and joining Smithkline Beecham where he held a number of finance roles again in the UK and the USA. He then moved to Enodis as director of planning & control and later chief financial officer, Europe and rest of world.

Debbie White replaced Adrian Ringrose as chief executive in March to try reverse the fortunes of the contractor.

However, a fresh profit warning was issued last week amid expectations that the cost of quitting its troubled Energy from Waste (EfW) contracts will now “significantly exceed” the £160 million it had expected.

Interserve chairman Glyn Barker said: “Following the appointment of Debbie White as CEO, Mark’s appointment is the next step in strengthening our top team to lead the transformation of Interserve. I am delighted to welcome Mark. His personal style and breadth of his experience will bring great value to the Group.”

Interserve chief executive officer, Debbie White, added: “I’m delighted to have Mark joining the team at Interserve. As we develop and execute the Group’s strategy Mark’s impressive wealth of leadership, financial and investor relations experience will be crucial in supporting the growth of our business and delivering value to our shareholders.”
