Annual Reserves and Resources and expected impairment

• Total 2P reserves reported at 4.5 MMboe, down from 5.5 MMboe in FY25
• Net downward revisions of 0.4 MMboe due to updated assessments
• Non-cash impairment expected at $3-$5 million for Maari and Sampang assets

Cue Energy Resources Ltd released its Annual Reserves and Resources statement for FY26, reporting total 2P reserves of 4.5 million barrels of oil equivalent (MMboe) as at 30 June 2026. This decrease from 5.5 MMboe in FY25 reflects 0.6 MMboe of production and net downward revisions of 0.4 MMboe following updated technical and commercial assessments. The company expects to recognize a non-cash impairment of approximately $3-$5 million in its FY26 financial statements for Maari and Sampang assets. Additionally, $4 million of capitalised costs associated with the Paus Biru project have been written off due to Cue's decision to withdraw from the project. The reserves statement was prepared in accordance with SPE PRMS 2018 using Horizon Oil Limited's reserves management and review processes.

Expected non-cash impairment of $3-$5 million for FY26

Cue remains focused on disciplined investment and maximising the value from its portfolio of high-quality oil and gas assets.
