Chairman’s Statement

It is worth recalling where this Company stood not long ago. The fields Buccaneer inherited were in decline, costs were high, and the business was loss-making at the field level.

2026 actually began poorly. Low oil prices in the first quarter forced us to shut in a number of high-volume, low-return wells while we transitioned them from Electric Submersible Pumps to lower-cost rod pumps. It was not an easy decision at the time.

As the period progressed, both production and oil prices improved, and the first half of 2026 marks a genuine turning point: for the first time, our core production operations generated a profit. This was not by accident or simply due to oil prices. It resulted from sustained cost discipline and the acquisition of the Carlisle-1 well, which has paid back rapidly and continues to perform strongly.

In June 2026, our lender, WAFD Bank, completed an independent borrowing base review. Total net proved reserves increased by 18% and forecast cash flow by 27%, with an NPV9 of US$11.8 million under WAFD's own conservative pricing. For proved undeveloped assets specifically, largely reflecting the increased equity position secured through the Carlisle-1 acquisition, the increase was a substantial 68%.

This is independent confirmation, from a lender with every incentive to be cautious, of the progress this Board believes it has delivered. Overall, the first half of 2026 saw a combination of improved asset performance, attractive acquisitions, and much higher oil prices, which put the Company in a much stronger financial position.

Pine Mills is not, on its own, the most glamorous asset in this sector. It is not meant to be. It is a mature field with a low decline rate and low operating costs, and it does exactly what we need it to do: generate cash. The Organic Oil Recovery programme has already delivered encouraging early results, and the Fouke waterflood, once online later this year, is expected to add further volumes. Even modest incremental barrels at current oil prices represent meaningful additional upside for shareholders.

It is, however, what has happened since the period end that this Board regards as the most significant news for shareholders. Following an equity fundraising of £350,000 in March, in August 2026 we completed a further equity fundraise of £460,000, at no discount to the prevailing mid-market price, alongside the announcement of Buccaneer's expansion into European onshore gas.

This marks a fundamental shift in what this Company is. Buccaneer began as a single-asset Texas operator working to stabilise a declining field. It is now building toward something materially different: a business with a self-funding US production base and a genuine second growth engine in European gas, targeting a scale of opportunity that dwarfs anything achievable through the US asset alone.

That is where this Company is now focused. It is funding the technical and permitting work required to convert our screened opportunities into a producing European gas portfolio. This was not a step taken lightly, nor was it taken without considerable groundwork beforehand. It is the most significant strategic development in the Company's history; the Board's focus is now entirely forward-looking. I encourage every shareholder to read the details of it in the Chief Executive's report that follows.

I’d like to thank the Buccaneer team and our contractors for their ongoing work, and most importantly, our shareholders for their continued support.

Dr Stephen Staley

Chief Executive Officer’s report

Production in the first half was 11,587 barrels of oil net, including the Carlisle-1 well, which has paid back rapidly and continues to perform ahead of expectations. Revenue rose 15% to $1,027,000, while a 35% reduction in production costs, aided by our transition from Electric Submersible Pumps to lower-cost rod pumps, drove the field to gross-level profitability for the first time. As previously reported, positive monthly net cash flow was generated from the Pine Mills and Fouke assets in May and June 2026 and is expected to continue, enabling the Company to comfortably service interest on its legacy obligations while reducing outstanding debt and strengthening its financial position. Cash at 20 September 2026 stood at $150,000, and costs remain tightly controlled. Looking ahead, we expect the Fouke waterflood and our expanding Organic Oil Recovery programme to be the key drivers of the next material increase in production and reserves in the US.

Beyond Texas: Building a Second Pillar of Growth

Since the period end, Buccaneer has taken perhaps the most significant strategic step in the Company's history: a decisive move to establish a materially larger, second pillar of growth in European onshore gas, funded by the cash-generative Texas base we have spent the past two years building.

The backdrop could scarcely be more compelling. The huge reduction of Russian pipeline gas volumes and disruption to Middle Eastern LNG supply have left large parts of Europe structurally short of gas, with prices trading at a significant multiple of US levels. At the end of 2027, all gas imports from Russia will be banned in much of Europe. For much of the past decade, restrictive policy effectively closed the door to new onshore development across many European jurisdictions, leaving genuine subsurface opportunities stranded and unexploited. That door is now reopening, as energy security has moved from a peripheral concern to a first-order policy priority for host governments across the continent. Combined with a decade of advances in seismic reprocessing and drilling technology, the result is a set of opportunities that simply did not exist, commercially or technically, even five years ago.

Buccaneer's ability to capitalise on this rests on the calibre of the team we have assembled. Roberto Bencini, working alongside Chairman Dr Stephen Staley, brings over 40 years of international exploration experience and a personal track record that includes some of the industry's most significant discoveries. Roberto and his team bring a rare combination: decades of hands-on exploration success across multiple basins, and the geological memory that comes with it, knowledge of what has worked, what hasn't, and why, that a newly assembled team simply could not replicate.

That team has already screened close to 300 European gas opportunities against a disciplined set of criteria: high-quality subsurface assets, proximity to existing high-pressure infrastructure, shallow and cost-effective depths, and a genuine, unobstructed path to development. From that process, we have identified a focused shortlist and are targeting an initial portfolio of up to three low-cost entry projects, with combined P50 potential of c.250 bcf and an estimated NPV10 of approximately $500 million. Permitting applications are in progress across the Company's shortlisted projects, and the Board will provide updates on discrete steps as appropriate.

To put that figure in context: against a Company whose current market capitalisation stands at a small fraction of that target NPV10, the scale of the opportunity, if delivered, would represent a transformational re-rating for Buccaneer shareholders. The Board intends to fund this development through a disciplined, capital-light strategy: securing acreage, advancing technical work, and bringing in partner capital as projects mature.

We believe this represents a genuine step-change in scale for Buccaneer, and one the market has, so far, only begun to price in. Watch this space.
