• Mereenie gas sales agreement LOI with Power and Water Corporation has expired
• Existing gas supply agreement remains in place until 2030
• Infill drilling program suspended, reducing 2026 capex by ~USD 5 million
• Focus shifts to gas marketing and contracting discussions with other parties

Horizon Oil Limited (ASX: HZN) has announced that the Letter of Intent (LOI) with the Northern Territory's Power and Water Corporation (PWC) relating to a proposed new Mereenie gas sales agreement has expired, and the parties have not reached agreement on terms for a replacement arrangement. The expiry of the LOI does not impact Horizon's existing gas supply agreement with PWC, which remains in place and continues through to 2030. The proposed new agreement was intended to underwrite the drilling of two additional infill wells to meet nearer-term gas supply requirements. In the absence of a new agreement, the Joint Venture has determined that this additional near-term drilling is no longer required and will therefore suspend further work on the proposed infill drilling program, reducing Horizon's forecast capital expenditure for 2026 by approximately USD 5 million. Notwithstanding this decision, well planning is well advanced, with long-lead items on hand and drilling contracts in place, enabling the Joint Venture to progress the new wells at relatively short notice should market conditions or gas contracting outcomes change. The Joint Venture will now focus its efforts on gas marketing and contracting discussions with other market participants to secure commercially acceptable gas sales arrangements. Horizon will continue to update the market on material developments in due course.
