As part of the transformation of Synthomer, Adrian led a number of successful non-core disposals and strategic acquisitions, including the acquisition and integration of PolymerLatex, a major competitor of Synthomer, in 2010 for £376 million, extracting annual cost synergies of over £20 million per year. In recognition of his efforts, he was awarded Turnaround of the Year at the 2011 UK PLC Awards.

Prior to his role at Synthomer, Adrian was a divisional chief executive at DS Smith, a manufacturer of paper and packaging products, for seven years. There he set-up a new plastics division, growing its turnover to £200 million organically and through the acquisition of six international businesses.
