Ross Glover, Chief Executive Officer, said:

"The core of our strategy is simple: to create value for shareholders through disciplined execution, cash generation, and the creation of long-term growth opportunities.

The past few years - and especially recent global events - have made clear the strategic value of secure, domestic energy production. UK-produced oil and gas are not just geopolitical necessities; they can increase our industrial competitiveness, improve economic resilience, and build geopolitical independence. Our onshore operations provide safe, reliable, domestic energy with local economic benefits - and they generate the cash flow that underpins our reinvestment and shareholder return potential.

We are focused on optimising our existing producing assets, seeking to reduce operating costs whilst future proofing the operations and maintaining our strong HSE record.

At the same time, we are executing on our long-term growth platform: geothermal energy.

The UK geothermal sector is underdeveloped, but the demand drivers heat decarbonisation, energy security, and long-term predictable pricing are all intensifying. Our early entry and technical know-how give us a strong competitive edge. Our pipeline of private and public sector projects is growing, and we are working with credible partners like the NHS, Veolia and Bring Energy to mature the pipeline.

In Croatia, we benefit from a supportive regulatory and investment climate for geothermal. Our licenses cover prospective areas, and we are finalising technical de-risking to enable phased development. The Croatian market offers access to scalable power opportunities in a jurisdiction that welcomes clean energy investment capital.

As we look ahead, our value creation strategy remains clear and focused:

· Maximise cash returns from UK oil and gas operations to fund growth and improve financial resilience

· Grow a high-quality geothermal platform with scalable, de-risked opportunities in the UK and Croatia

· Maintain capital discipline and agility, with focus on value creation

We are uniquely positioned to deliver value from cash-generative UK oil and gas operations, while building a diversified energy business that can thrive in multiple market scenarios. Our geothermal activities are not a pivot away from hydrocarbons they are a logical, deployment of our core strengths in subsurface, permitting, and infrastructure development into a growth area.

This is about building a broader, more resilient business one that can generate sustainable returns across energy cycles and policy environments. Thank you to our shareholders for your continued support. Everything we are doing is focused on protecting and growing shareholder value."
