Change of External Auditor

10 August 2022 Change of External Auditor Contact Energy advises that it has accepted the resignation of KPMG as external auditor of the company with effect from 15 August 2022. Ernst & Young (EY) will be appointed as the group's new external auditor on the same day for the financial year commencing 1 July 2022. KPMG has been Contact's external auditor since 2005. The decision to change the auditor in no way reflects on the performance of KPMG. Rather we consider it is good governance practice for a company to change auditor from time to time and accordingly we have adopted a policy that the maximum tenure of any external audit firm is 15 years. Contact would like to thank KPMG for their service over the last 17 years. EY's appointment follows a formal request for proposal process that was that was overseen by Contact's Board Audit & Risk Committee. We are looking forward to working with EY and the fresh insights it might bring. -ends- 1/ MORE INFORMATION: Investors: Matt Forbes GM Corporate Finance +64 21 072 8578 Media: Julia Stewart Communications +64 21 869 537 End CA:00396751 For:CEN Type:ADMIN Time:2022-08-10 14:24:11
