While there is no certainty that a transaction will complete, the non-binding offer meets our core objectives: a full carry of the appraisal programme and early-stage development of Patardzueli-Samgori, a field with over 1 Tcf of 2C contingent gas resources, with material upside across the Rustavi and Teleti fields as well as the South Dome exploration prospect which are all located within 15 miles of the South Caucasus Pipeline, one of Europe's major gas import corridors.

We look forward to updating shareholders as negotiations advance and as we continue to progress activity across the wider portfolio."
