Caltex Australia has appointed its chief financial officer (CFO) Matthew Halliday to the position of interim CEO after failing to find a replacement for current leader Julian Segal, who retires next week. “Given our recent announcements regarding the receipt of revised and new proposals to acquire Caltex, it is not possible for us to complete this search at this time,” chairman Steven Greg said. Segal announced his retirement plans in August and will now leave the role on March 2.
