Healius has appointed Jan Van Rooyen – former chief executive of South Africa’s AMPATH – as its new pathology boss amid an attempted hostile takeover from smaller rival Australian Clinical Labs. Dr Van Rooyen will start at the company as its group executive, Healius Pathology, on June 1, replacing John McKechnie as part of “refresh” of its executive leadership. His appointment follows Healius’s board blasting ACL’s nil-premium offer as “plainly inadequate” and questioned the $95m in cost savings that ACL said it could deliver from a merged group.
