What Prospex Energy does

Prospex Energy Plc is an AIM-listed investment company (ticker PXEN) incorporated in England and Wales that provides public market investors with exposure to a portfolio of onshore European oil and gas assets across the asset lifecycle, from exploration through production. Founded in 2010 and rebranded from PXOG to its current name in July 2020, the company holds five core investments: a 37% working interest in the producing Selva Malvezzi concession in Italy (operated by Po Valley Energy), 100% of the producing El Romeral gas-to-power project in southern Spain via wholly owned subsidiary Tarba Energía, a 7.5% indirect interest in HEYCO Energy Iberia which operates the Viura gas field — Spain's largest producing gas field — also in Spain, 100% of the Tesorillo exploration concession in southern Spain via Tarba Energía, and 100% of the San and Dunajec exploration licences in southern Poland via PXEN Tatra, awarded in April 2026.

The company's underlying technology is conventional upstream oil and gas — seismic interpretation, well logging, reservoir evaluation, and gas processing — executed by an in-house geoscience team and through operating partners. Production assets are already connected to established national infrastructure: Selva Malvezzi ties into the SNAM pipeline network in Italy, while El Romeral and Viura feed into Spain's national gas network, with El Romeral additionally operating an on-site three-engine gas-to-power facility supplying the Spanish electricity grid.

Prospex generates revenue from the sale of produced natural gas and electricity into national pipeline and grid networks under commodity-based pricing. Customer engagement with investors is conducted through regulatory news releases (RNS), investor presentations, the corporate website, and AGM materials, while commercial relationships are maintained with joint venture partners and operators responsible for field development and production. The company has financed its growth through a series of small AIM placings and convertible loan notes since 2016.
