Horizon Oil Ltd reported its FY26 Half Year Results, highlighting key achievements and strategic delivery. The company is entering its 6th consecutive year of distributions, totalling AUD 17.0 cents per share since 2021. The acquisition of Thailand assets in August 2025 added ~2,000 boe/d and ~3.5 MMboe (2P) to the portfolio, with further growth opportunities under active review. Asset development is underway across the portfolio, including a liquids-handling upgrade in Block 22/12, two gas infill wells planned at Mereenie, workover activities at Maari, and the Nam Phong booster compressor FID and Sinphuhorm tie-ins in Thailand. Financially, Horizon delivered Underlying Revenue of US$54.2 million and EBITDAX of US$28.6 million, with a statutory profit after tax of US$2.4 million and operating cashflow of US$25.1 million.
