Gas production and revenues from PM-1 gas facility in the Selva Malvezzi Production Concession

Highlights

· Stable production performance from the Podere Maiar-1 (PM-1) well throughout the quarter, in line with expectations, supporting continued strong operating cashflows.

· Progress made on Environmental Impact Assessment (EIA) updates and development planning for the Casale Guida-1d, Ronchi-1d, Bagnarola-1d, and Selva Malvezzi-1d wells, incorporating feedback from the Ministry.

· Completion of the 3D geophysical survey, with data currently undergoing processing by Schlumberger Italy for delivery of a final 3D seismic volume for in-house interpretation

Tom Reynolds, Prospex's CEO, commented:

"The consistent production and strong cash flow from Podere Maiar-1 is very welcome and underpins activity across Prospex wider portfolio of assets on which we expect to provide a short quarterly update in due course.

"European gas prices have been elevated in the period, influenced by geopolitical tensions in the Middle East, underlining the need for secure, domestically sourced energy. With operations and exposure across key markets including Italy, Spain and Poland, the Company is well positioned to benefit from this supportive pricing environment while continuing to build value through its diversified European presence."

Podere Maiar-1 (PM-1) Production

Production performance remained consistent during the quarter:

· Gross gas production totalled 7.26 million scm, generating €3.1 million (gross) in revenue.

· Net production attributable to Prospex at 37% was 2.69 million scm and €1.16m in revenue.

· Average daily production was approximately 80,000 scm/day, with only minimal downtime for scheduled maintenance in January.

Cumulative production since commencement has reached 72.9 million scm (gross), exceeding the certified P1 reserves outlined in the July 2022 CPR.

The average realised gas price for the quarter was €0.43/scm. Prices strengthened toward the end of the period, reflecting tightening global energy markets and heightened geopolitical risk associated with the conflict in Iran.

Royalty expenses of €116k were accrued during the quarter, with payments scheduled annually in arrears (next payment due Q2 2026).

Broader Selva Development Programme

· The Operator continues to progress development planning for four key wells within the concession:

o  Casale Guida-1d (Selva North)

o  Ronchi-1d (South Selva)

o  Selva Malvezzi-1d (East Selva)

o  Bagnarola-1d (Riccardina)

· The EIA submitted in December 2024 is currently being updated to incorporate Ministry feedback and expanded project scope, including facilities, pipelines, and upgrades to the Podere Maiar field. Specialist studies requested by the EIA Commission are ongoing and are expected to be submitted in Q2 2026.

Notes

Prospex Energy PLC is an AIM-quoted investing company focused on high-impact onshore and shallow offshore European opportunities with short timelines to production. The Company's strategy is to acquire undervalued projects with multiple, tangible value trigger points that can be realised within 12 months of acquisition and then apply low-cost re-evaluation techniques to identify and de-risk prospects. The Company will rapidly scale up gas production in the short term to generate internal revenue, which can then be deployed to develop the asset base and further increase production.
