9-Months 2025 Production and adjusted EBITDAX

London, 27 October 2025 - Alongside today's announcement of the launch of an offering of € 400 million senior secured notes, Energean plc (LSE: ENOG, TASE: א) is pleased to provide an update on recent performance for Energean together with its subsidiaries on a consolidated basis (the "Group") in the 9-months to 30 September 2025. Energean's Q3 Trading Statement & Operational Update is planned for release at the end of November 2025 as usual.

· Increase in production quarter-on-quarter, with Group output rising 35% to average 176 kboed in Q3 2025 compared to 131 kboed in Q2 2025.

o Strong production performance in August 2025 continued into September 2025, with Group output averaging 178 kboed across both months. This reflects robust summer gas demand in Israel, where production averaged 140 kboed during the same period.

· Average production for the nine months ended 30 September 2025 was 151 kboed (85% gas), in line with full year guidance of 145-155 kboed, compared to 156 kboed (83% gas) for the nine months ended 30 September 2024.

o Production for the period was down year-on-year due to the temporary suspension of production in Israel in June 2025.

· Adjusted EBITDAX was $828 million for the nine months ended 30 September 2025, compared to $894 million for the nine months ended 30 September 2024.

o This was primarily driven by lower sales in Israel, impacted by the planned shutdown for essential works for the second oil train development in March 2025 in addition to the Ministry-ordered suspension of production for security reasons in June 2025, and lower Brent prices.
