Completion of Carlisle-1 Acquisition

Buccaneer Energy (AIM: BUCE), the international oil & gas exploration and production company with development and production assets in Texas, USA, is pleased to announce that it has completed the acquisition of a 100% working interest in the Carlisle-1 well located in the Fouke area of the Pine Mills field (the "Acquisition"). The transaction closed on 13 March 2026, with an effective date of 1 January 2026.

The Acquisition was partially funded from the proceeds of the £350,000 fundraise previously announced on 2 March 2026. Read the full announcement here.

Carlisle-1 Well Highlights

·	100% working interest acquired in the Carlisle-1 well.
·	Immediate production of approximately 25 barrels of oil per day (bopd).
·	Company production increases to approximately 155 bopd.
·	Carlisle-1 features low operating costs of US$6.23/barrel (bbl).
·	Strong netback of cUS$65/bbl at current field prices.
·	Estimated net cash flow of approximately US$50,000 per month at current oil prices.
·	PV10 value of US$910,540 based on independent reserve report using bank price deck (see below).
·	Approximately 51,000 barrels of proved reserves (third-party estimate) before waterflood, 256,000 with the waterflood.
·	Increases Buccaneer's interest in the proposed Fouke waterflood unit from approximately 33% to greater than 50%.

Carlisle-1 Asset

The Carlisle-1 well (the "Well") is located within the Pine Mills Field in East Texas, adjacent to Buccaneer's existing Fouke area wells and producing from the same reservoir horizons as the Fouke 1 and Fouke 2 wells.

The Well is currently producing approximately 25 bopd, generating strong cash margins due to low operating costs. Based on current field prices of approximately US$92/bbl, the Well delivers a netback of approximately US$65/bbl, equivalent to approximately US$50,000 in monthly net cash flow.

Operating costs for the Well were approximately US$6.23/bbl in 2025, highlighting the strong margin profile of the asset.

A third-party reserve report estimates proved developed producing (PDP) reserves of approximately 51,000 barrels of oil, with a PV10 valuation of approximately US$910,540 using a conservative bank (WAFD) price deck (See below). This estimate does not include any reserves associated with the Fouke area waterflood, which are anticipated to be approximately 225,000 barrels under waterflood development or from Buccaneer's Organic Oil Recovery ("OOR") programme.

The report was prepared by APN Energy to the SPE PRMS standard and dated 2 March 2026.

Category	Gross Oil and condensate (Mbbl)	Net oil and condensate (Mbbl)

Total Proved	$1,224,120	$910,540

The Acquisition further consolidates Buccaneer's position within the proposed Fouke waterflood unit, where the Company anticipates its working interest will increase from approximately 32.5% to greater than 50% following the addition of the Carlisle-1 well.

The Well is expected to benefit from both waterflood development and Buccaneer's OOR programme, which has already demonstrated significant production uplift within the Pine Mills field.

Paul Welch, Buccaneer Energy's Chief Executive Officer, said:

"The completion of the acquisition of the Carlisle-1 well immediately increases our production and cash flow while strengthening our strategic position within the Fouke area of the Pine Mills field.

Carlisle-1 is a high-margin producing asset with low operating costs and attractive reserves and increases our interest in the proposed Fouke waterflood unit to greater than 50%, enhancing our operational position as we continue to develop the area.

The Acquisition increases our working interest production to approximately 155 bopd, and with strong oil prices and low onshore operating costs, Pine Mills continues to generate attractive cash margins for the Company. Based on the latest reserve update using the conservative WAFD bank price forecast (shown below), it increases our current NPV10 PDP reserve value to approximately US$10.5 million.

Carlisle-1 also offers attractive capital efficiency, with a projected payout period of approximately 9 months at current pricing.

The Board believes Buccaneer's current market capitalisation of approximately £1.55 million does not yet reflect the value of its existing producing reserve base, as set out in the latest reserve update using the conservative WAFD bank price forecast, and before any contribution from recent oil price increases, the proposed Fouke waterflood unit, OOR optimisation or broader field development upside. Our focus is on disciplined execution to narrow that value gap through production growth, cash generation, and enhanced recovery initiatives."

Glossary

bopd	Barrels of oil per day
Gross Production	Production at a total project level (100% basis) before royalties
Net Production	Net production attributable to a participant's Working Interest before royalties
Royalty	A type of entitlement interest in a resource that is free and clear of the costs and expenses of development and production to the royalty interest owner. A royalty is commonly retained by a resources owner (lessor/host) when granting rights to a producer (lessee/contractor) to develop and produce that resource. Depending on the specific terms defining the royalty, the payment obligation may be expressed in monetary terms as a portion of the proceeds of production or as a right to take a portion of production in-kind. The royalty terms may also provide the option to switch between forms of payment at discretion of the royalty owner.
SPE	Society of Petroleum Engineers
SPE PRMS	A standard for the definition, classification, and estimation of hydrocarbon resources developed by the Oil and Gas Reserves Committee of the Society of Petroleum Engineers and named the Petroleum Resource Management System
Proved Reserves	An incremental category of estimated recoverable quantities associated with a defined degree of uncertainty. Proved Reserves are those quantities of petroleum that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs and under defined economic conditions, operating methods, and government regulations. If deterministic methods are used, the term "reasonable certainty" is intended to express a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will equal or exceed the estimate.
Undeveloped Reserves	Those quantities expected to be recovered through future investments: (1) from new wells on undrilled acreage in known accumulations, (2) from deepening existing wells to a different (but known) reservoir, (3) from infill wells that will increase recovery, or (4) where a relatively large expenditure (e.g., when compared to the cost of drilling and completing a new well) is required to recomplete an existing well.
Working Interest	A participant's equity interest in a project before reduction for royalties or production share owed to others under the applicable fiscal terms.
