About Prospex Energy Plc

Prospex Energy Plc is an AIM-quoted investment company focused on European Natural Gas and power projects. Its portfolio includes a 37% working interest in the Selva Malvezzi production concession in northern Italy, a 7.24% interest in the Viura gas field in northern Spain and full ownership of Tarba Energia, owner of the El Romeral gas-to-power plant in southern Spain.

In 2026 the company added two onshore exploration licences in Poland, San and Dunajec, which include the Mniszow oil discovery. Chief Executive Tom Reynolds took up his post in February 2026.

The company's model is to hold non-operated interests alongside experienced operators, which keeps overheads low and allows exposure to several fields at once. It describes its Assets as low operational risk, onshore and close to existing infrastructure.

Key Reasons Behind the 12 Nov 2026 Move

European gas prices have remained supportive, and the company reported a record month of Revenue from Selva Malvezzi in August, with a realised gas price of EUR 0.67 per cubic metre and gross monthly revenue across the portfolio of EUR 795,800.

A new 12-month gas sales agreement with Hera Trading began on 1 Oct 2026, providing a route to market for locally produced gas.

Selva Malvezzi in Italy

The Podere Maiar well has been producing since July 2023 at around 80,000 cubic metres per day. The concession holds 13.4 billion cubic feet of gross 2P reserves, with 5.0 billion cubic feet net to Prospex.

A four-well drilling programme is planned, and the environmental impact assessment was declared admissible by the Italian ministry in September 2026. A 3D seismic dataset is being interpreted ahead of the planned 2027 campaign.

Spain: El Romeral and Viura

El Romeral generated August revenue of EUR 179,400 and has become self-sufficient on a cash basis, supported by consistent production and higher electricity prices. A new transformer is expected to reduce operating costs.

At Viura, the operator reported EUR 4.15 million of cash revenue in the second quarter, and planning for a 2027 development programme is under way.

Poland and New Growth

The Polish licences give the company exposure to a new onshore region. Work has focused on collating historical data and designing completions for the Mniszow oil discovery.

Management is seeking partners that can provide non-dilutive funding to support the 2027 programme.

Funding and Partnership Approach

Management has said that activity across its assets is expected to converge around the end of 2026, with Capital spending falling into 2027. It aims to use revenue from producing assets and non-dilutive funding to help support that plan.

A convertible Loan note issue of about £2 million in early 2026 exceeded its original target by 25% and funded the company's share of seismic processing and the new Polish licences.

Areas to Watch

Investors will likely follow drilling permits and timing in Italy, gas pricing, production at Viura, progress in Poland and the search for development partners.

Operational detail at each asset is also useful, including monthly production at Selva, electricity output at El Romeral and field availability at Viura. The company has said it will update shareholders on the Polish licences through investor events and announcements.

Prospex Energy Plc continues to keep the market informed through regular announcements and its scheduled reporting calendar, which investors can follow for further developments.
