ASX/Media Release

11 May 2016

Origin confirms timing of Karen Moses’ retirement and establishment of a CFO role reporting to the MD

Origin Energy Ltd (Origin) today announced the timing of Ms Karen Moses’ retirement from Origin and the establishment of a Chief Financial Officer role reporting directly to the Managing Director.

At the 2015 AGM last October, Ms Moses advised of her intention to retire in 2016 to pursue a non-executive director career. Ms Moses’ commitments external to Origin have built to the extent that it is now appropriate for her to step down from her current role as Executive Director, Finance and Strategy, effective Monday 16 May, 2016. Ms Moses will continue her employment with Origin until her retirement at the end of August to provide support through a transitional period and complete work on a number of strategic priorities.

Origin is currently conducting a search for a permanent appointment to the CFO role covering both internal and external candidates. Until a permanent appointment has been decided upon, Origin’s current Group Financial Controller, Mr Gary Mallett will act in this role.

Origin’s Managing Director, Mr Grant King said, “Ms Moses has made an invaluable contribution to the growth and development of Origin for more than 20 years and we wish her well as she nears her well-earned retirement.”
