Half-year Results

Block Energy plc, the development and production company focused on Georgia, is pleased to announce the interim results for Block Energy plc and its subsidiaries (the "Group") for the six months ended 30 June 2025.

Highlights:

• Operational man-hours worked of 136,065 (1H 2024: 144,072 man-hours) with zero lost time incidents (1H 2024: One).
• Net cashflow remained operationally positive throughout the period.
• The Group recorded a loss for the period of $639,000 (1H 2024: profit of $2,000) and EBITDA of $81,000 (1H 2024: $645,000). The result reflects the fall in oil prices in the period together with reduced oil inventory levels at period end of $498,000 (1H 2024: $23,000), which increased cost of sales.
• Further reductions in G&A spending to $1,010,000 (1H 2024: $1,372,000) demonstrating effective cost control despite ongoing work on strategic projects.
• Production remained stable, with total production of 87.5 Mboe comprising 66.4 Mbbls of oil and 21.1 Mboe of gas (1H 2024: 82.8 Mboe, comprising 61.3 Mbbls of oil and 21.5 Mboe of gas).

o Average daily production of 483 boepd (1H 2024: 455 boepd).

• Oil sales of 49.9 Mbbls with revenue of $3.02 million, representing a weighted average price of $60.5 per barrel (1H 2024: Oil sales of 46.6 Mbbls with revenue of $3.3 million, representing a weighted average price of $71 per barrel). Declines in realised prices were caused by a reduction in the Brent benchmark price.
• Gas sales of 82.2 MMcf with revenue of $0.36 million, representing a weighted average price of $4.4/Mcf (1H 2024: 93.5 MMcf with revenue of $0.38 million, representing a weighted average price of $4.1/Mcf).
• Oil in inventory net to the Company at the end of the period was 8.27 Mbbls (1H 2024: 12.1 Mbbls).
• Cash position of $845,000 as at 30 June 2025 (31 December 2024: $1,136,000).

Good progress was made in advancing the strategic projects in the first half:

o Acquired the operational rights to Samgori South Dome at Lower Eocene and Upper Cretaceous intervals for nil cost through its incorporation into XIB. This acquisition added 574 BCF 2U unrisked mean prospective recoverable resources to Project III.

o Acquired a 10% Participating Interest in the high-impact XIQ PSC located to the north of our XIB licence, adding a net 59 MMboe 2U unrisked mean prospective recoverable resources to Project IV.

o Progressed the CCS project with various studies, lab and operational milestones met.

o Continued to see good engagement on the Project III farm-out.

Post period events:

The Company continued with its strategy of asset development post-period:

• Successfully injected CO2 into the reservoir as part of the ongoing carbon mineralisation pilot.
• Concluded negotiations for the farm-in of a leading international independent E&P company to the XIQ licence, with completion expected Q4 2025 - Q1 2026.
• Spud well KRT-39ST on Project I.

Commenting, Paul Haywood, Block Energy Chief Executive Officer said:

"This has been an important time for Block and since the period end and momentum has accelerated: we have agreed terms with a leading international E&P to farm into Project IV, successfully delivered the region's first CO₂ injection under our CCS pilot, secured the addition of South Dome and significantly boosting Project III's gas resources, as well as spudding KRT-39ST. Together, these achievements represent a major endorsement of our portfolio and Georgia's investment potential, positioning Block strongly for its next phase of growth. Looking ahead, our priorities are clear: complete the Project IV farm-out, progress Project III farmout, advance drilling across our various projects and CCS activity, and evaluate new ventures aligned with our capital-efficient strategy. Each of these represents a catalyst to deliver material shareholder value."

General information

Block Energy Plc, (the "Company") is a company registered in England and Wales (05356303), with its registered office at Eccleston Yards, 25 Eccleston Place, London SW1W 9NF.

The Condensed Consolidated Interim Financial Statements of the Group, which comprises Block Energy plc and its subsidiaries (the "Group"), for the six-month period from 1 January 2025 to 30 June 2025, were approved by the Directors on 22 September 2025. The Group's principal activity is oil and gas exploration, development and production.

The Company's shares are traded on AIM and the trading symbol is BLOE.

These condensed interim financial statements do not comprise statutory accounts within the meaning of section 434 of the Companies Act 2006. Statutory accounts for the year ended 31 December 2024 were approved by the Board of Directors on 21 May 2025 and delivered to the Registrar of Companies. The auditor's report on those financial statements was unqualified but did include a reference to the material uncertainty surrounding going concern, to which the auditors drew attention by way of emphasis of matter and did not contain a statement under s498 (2) - (3) of Companies Act 2006.

The Company's auditors have not reviewed these condensed consolidated interim financial statements.

Basis of preparation

Management has prepared these interim accounts in accordance with IFRS accounting policies as applied at 31 December 2024 (without the disclosure requirements of IFRS). They do not include all of the information required in annual financial statements and should be read in conjunction with the consolidated financial statements for the year ended 31 December 2024 and any public announcements made by Block Energy Plc during the interim reporting period. All amounts presented are in thousands of US dollars unless otherwise stated.

The comparatives are the six-month period ended 30 June 2024, except for the Condensed Consolidated Statement of Financial Position, where the comparatives are as at 31 December 2024.

The accounting policies adopted in this half-yearly financial report are the same as those adopted in the 2024 Annual Report and Financial Statements. There were no new or amended accounting standards that required the Group to change its accounting policies. The Directors also considered the impact of standards issued but not yet applied by the Group and do not consider that there will be a material impact of transition on the financial statements.

Going concern

As part of their going concern assessment, the Directors have examined multiple scenarios in which oil prices and/or future production levels fall substantially and have concluded that it remains possible that future revenues in at least some scenarios might not cover all operating costs and planned capital expenditures, creating a material uncertainty that may cast doubt over the Group's ability to continue as a going concern.

Whilst acknowledging this material uncertainty, the Directors remain confident of making further cost savings if required and, therefore, the Directors consider it appropriate to prepare the financial statements on a going concern basis. The financial statements do not include the adjustments that would result if the Group were unable to continue as a going concern.

Operating segments

The Group is engaged in the appraisal and development of oil and gas resources in Georgia and is therefore considered to operate in a single geographical and business segment.

These warrants are exercisable at any time up until 30 July 2027 and have an exercise price of 0.85 pence per ordinary share.

$124,000 of this interest charge was capitalised during the first half of 2024 to reflect borrowing costs directly associated with assets at pre-commercial production stage.
