Notes to Editors

Block Energy plc is an AIM-quoted independent oil and gas production and development company focused on building a diversified portfolio of high-impact energy assets.

The Company's core operations are in Georgia, where it holds interests in seven Production Sharing Contracts covering an area of 4,256 km² in the central part of the country. These include the XIB licence, which has over 2.77TCF of 2C contingent gas resources, with an estimated Net Present Value 10 ("NPV") of USD 2.2 billion, in the Patardzueli-Samgori, Rustavi and Teleti fields. (Source: IER, OPC 2024 & Internal estimates).

The Company is structured around a multi-project approach, progressing assets across different stages of development, hydrocarbon type, and reservoir characteristics. This approach is designed to deliver a balanced portfolio of production growth, field redevelopment, new discoveries and the commercialisation of substantial gas resources. The goal is to deliver on multi-TCF gas assets, strategically well located for the key EU market, supported by partner funding and cash from existing producing assets.

The Company has completed a farm-out of licence XIQ to Aspect Georgia, under which Aspect may earn up to a 92.5% working interest through the completion of a staged, fully funded work programme.

In April 2026, the Company signed a Binding Framework Agreement with Zhijiang Sanning Energy Co. Ltd, one of China's leading chemical producers, in relation to the farm out of Project III. Project III comprises the Lower Eocene and Upper Cretaceous gas discoveries across Block's XIB and XIF licences in central Georgia. The proposed farm-out is expected to support the appraisal and development of these assets while reducing Block Energy's capital exposure.

Located near the Georgian capital of Tbilisi, Block Energy is well-positioned to contribute significantly to the region's energy landscape. This proximity facilitates seamless operations and underscores our commitment to the economic and energy development of Georgia.
