About Energean plc

Established in 2007, Energean is a London Premium Listed FTSE 250 and Tel Aviv 35 Listed E&P company with operations in nine countries across the Mediterranean and UK North Sea. Since IPO, Energean has grown to become the leading independent, gas-focused E&P company in the Eastern Mediterranean, with a strong production and development growth profile. The Company explores and invests in new ideas, concepts and solutions to produce and develop energy efficiently, at low cost and with a low carbon footprint.

Energean's production comes mainly from the Abu Qir field in Egypt, and fields in Southern Europe and the UK. The company's flagship project is the 3.5 Tcf Karish, Karish North and Tanin development offshore Israel, where it intends to use the only FPSO in the Eastern Mediterranean to produce first gas, commencing 4Q-2021. Energean has signed firm contracts for 7.4 Bcm/yr of gas sales into the Israeli domestic market, which have floor pricing, take-or-pay and/or exclusivity provisions that largely insulate the project's revenues against global commodity price fluctuations and underpin Energean's goal of paying a meaningful and sustainable dividend.

With a strong track record of growing reserves and resources, Energean is focused on maximising production from our large-scale gas-focused portfolio to deliver material free cash flow and maximise total shareholder return in a sustainable way. ESG and health and safety are paramount to Energean; it aims to run safe and reliable operations, whilst targeting carbon neutrality across its operations by 2050. These aspirations have been significantly advanced with the completion of the Edison E&P acquisition in December 2020.
