CUE Energy Resources Limited Annual Report 2026

New Zealand PMP 38160 (Maari/Manaia) CUE INTERESTS Cue 5% Operator OMV Production from Maari and Manaia fields net to Cue was 86 Mboe, with full field production reduced during the year due to workovers to MN1, MR3 and MR4 wells. The field achieved its highest monthly average production in five years, with average daily production of over 5,600 bopd recorded in August 2025. A significant milestone was achieved with the New Zealand Government approving a 10-year extension of Petroleum Mining Permit PMP38160 to December 2037. The permit extension enables the Joint Venture to continue safe, long-term production while assessing further opportunities for resource optimisation and field enhancement. The New Zealand Government continues its assessment of the Maari Joint Venture’s financial assurance arrangements for decommissioning, with ongoing engagement between the Joint Venture and the regulator. Indonesia SAMPANG PSC CUE INTERESTS Cue 15% Operator Medco Energi Production from the mature Oyong and Wortel gas fields continued to decline during the year with lower gas production as the fields progressed through the later stages of their production lives. The Operator continues to review available options to optimise output from existing wells. Installation of compression at the Grati gas plant to support production and recovery was significantly delayed during the year, impacting gas production levels. Compression has now been installed and is operational. During the year, Cue advised the joint venture partners in the Sampang PSC that it would not participate in the Paus Biru development and does not intend to remain in the Sampang PSC beyond the current permit expiry in December 2027.
