"Simon has had a long career at PwC and his knowledge of the financial markets, transactions and governance will be very valuable as we continue to grow Arecor. We also thank him for taking on the Chair position on the Audit & Risk Committee, an important role, especially in the life sciences sector. His insight as Arecor pursues its strategy to grow value will be especially helpful. To date, the Audit & Risk Committee has been ably overseen by Christine Soden who is now stepping away from Arecor. She will be missed by us all and we wish her all the best for the future."
