STATEMENT FROM THE EXECUTIVE CHAIRMAN

Transformation

The first half of 2025 saw Sound in its new role as minority co-venturer with Mana Energy and the National Office of Hydrocarbons and Mines (ONHYM) in the development of the Tendrara concession. In June, two new initiatives to diversify the Sound portfolio in Morocco were announced, both with experienced partners. Firstly, the formation of HyMaroc Ltd, www.HyMaroc.com, a company established to explore for Natural Hydrogen and Helium in Morocco and secondly a binding agreement to create a joint venture to produce and sell renewable energy via access to the medium voltage grid in Morocco. Leveraging our local knowledge and stakeholder relationships, Sound is now in a diversified position to perform a key role in Morocco's energy growth and transition plans.

Phase 1 Tendrara Micro LNG Project (mLNG) 

The Micro-LNG project continues to move from design, engineering and construction to installation and commissioning with first gas production now scheduled for Q4 2025. Mana Energy as Operator has enhanced the former Sound Energy local team with additional specific project delivery resources. The main contract with Italfluid GeoEnergy S.r.l (Italfluid) has been changed from a vendor financing contract to a traditional Engineering, Procurement and Construction (EPC) contract with commensurate reduction in daily operating costs. This has only been possible with the support of Mana Energy's financial capacity. Attijariwafa Bank has provided a $25 million debt facility to Mana Energy on behalf of the consortium to fund this contract conversion. Sound's share of this facility is $5 million.  Sound continues to support the Operator with certain services; however, it is recognised that Mana Energy is using its considerable Project delivery capacity to achieve first gas by year-end 2025.

ESG

Following the transfer of operatorship to Mana Energy, Sound Energy's Environmental, Social and Governance (ESG) commitments and activities associated with the Tendrara operations have been handed over to Mana Energy. Mana Energy continues to operate in an environmentally responsible manner and to support the local community. Governance continues to be a focus for the organisation, overseen by the Board of Directors. ESG related processes and commitments are core to Sound Energy's values and will be included in all new business opportunities. ESG remains at our core despite non-operator emissions attributable to Sound being de-minimis.

It is to our great sadness that our Health, Safety, Security and Environmental (HSSE) Manager, Sean Gallagher, passed away unexpectedly in July 2025 following a routine hospital operation. Sean was a much respected, liked and admired member of the Sound executive team at the Tendrara development with a wealth of experience in HSSE matters and extensive practical handling of risk management with 23 years' experience in the oil and gas industry. He will be sorely missed by all his colleagues.

Phase 2 Tendrara Processing and Pipeline Project 

The pipeline project has not progressed as promptly as Sound would have liked this year, however updating of the Front-End Engineering & Design (FEED) study and selection of EPC contractor, which remains the key outstanding CP for the debt closure, is now in the hands of the Mana Energy procurement team who have commissioned this work. Results of the FEED update is due this year such that Final Investment Decision (FID) can be taken thereafter.

Exploration

The Company and ONHYM have previously proposed extensions to the Anoual licence to the relevant Ministries and we continue to await approval. Similarly, Sound is in continued exclusive discussions with ONHYM for the Grand Tendrara licence through Operator Mana Energy and directly for Sidi Moktar Onshore licence. Sound Energy's costs are to be carried by Managem SA for the SBK-1 structure well and M5 exploration wells as per terms of the farm-out transaction. We continue to push for optimal licence terms and instigation of exploration drilling.

Corporate 

During the period Sound continued to optimise its costs. Zeus was appointed as NOMAD alongside its role as Corporate broker. Sound's former CFO resigned to pursue other opportunities, and the company hired Andy Matharu, a very experienced corporate financier with strong background in Petroleum Engineering to succeed as CFO. Andy joined the Company full time as of 1st September 2025, corporate balance sheet restructuring being his current primary focus. The company continues to engage with stakeholders and has held several live Q&A sessions.  The AGM was held on 17th June with all resolutions supported by shareholders.

Board

Mohammed Seghiri resigned as COO from the Company and the Board to join Managem SA, providing continuation of operations in Morocco. We thank Mohammed for his 8 years of service to Sound Energy.

Chairman (Executive)

OPERATIONS REVIEW

Tendrara Development

Sound Energy is pursuing the Field Development Plan underpinning the Tendrara Concession centred around the TE-5 Horst gas discovery. The development is progressing in two phases. Phase 1, the mLNG production scheme provides gas to industrial consumers. The planned Phase 2 pipeline development provides gas to power the state energy power stations. Phase 2 is centred around the installation of a 120km gas export pipeline to help fully unlock the gas potential of this region and lower the cost of development for future discoveries. Both phases address different markets in Morocco - the industrial energy user and the state power producer, both of which have strong and growing demand, with Tendrara gas playing an important role in supporting Morocco's strategy to lower carbon emissions. As Morocco continues to grow both industrially and domestically and as other fuel sources become scarcer in-country, there is opportunity to supply more of the energy mix. Morocco's imports of natural gas from Spain through the GME pipeline rose again in 2024.  In 2023 Morocco imported 9,472¹ GWh (approximately 0.965 BCM, 30.5 Bcf) of natural gas from Spain and in 2024 imports increased to 9,703¹ GWh (approximately 0.886 BCM, 31.3 Bcf).  In the first five months of 2025, imports have risen by 7% compared to the same period in 2024¹.

Progress of the Phase 1 Development Project mLNG

This first phase focuses on the existing TE-6 and TE-7 wells of the TE-5 Horst. First gas will be achieved by tying the currently suspended TE-6 and TE-7 gas wells with flowlines connected to the inlet of a skid mounted, combined gas processing and mLNG plant. Production from both wells will meet the 10 mmcf/d sales gas volume.

In 2021, the Company entered into a lease contract with Italfluid for the design, construction, commissioning, operation, and maintenance of the mLNG facilities under a 10-year lease arrangement. The mLNG facilities, which will also treat, and process raw gas produced from the wells prior to liquefaction, is the principal part of the surface facilities required to be built and operated as part of this first phase of development. Also in 2021, the Company entered into a Sale and Purchase Agreement with Afriquia Gaz to offtake the LNG produced.  The LNG will be delivered to on-site storage from the outlet of the mLNG facilities whereupon Afriquia Gaz will lift and take title for LNG for transportation, distribution and sale to the Moroccan industrial market.

Groundworks for the construction of the mLNG facility commenced March 2022 following completion of surveying and remediation works to the access road for the facility.  The raised foundation platform for the LNG storage tank, and pads for the skid mounted units, including the compressor package, were completed in 2023 along with the necessary piping and cabling for the firefighting system which have been installed along with fencing and lighting towers.  During 2024, installation of the necessary insulation and construction of the outer and inner tank shells of the tank commenced and were completed in 2025.  Facilities engineering and manufacturing continued to progress with major vendors under the Italfluid contract.  In 2023 the Company selected Gas to Liquid Equipment (GLE) to provide engineering and procurement services for the flowline system and associated well head facility equipment for the gas gathering system to transport the gas from the well heads to the mLNG plant.  During the first half of 2025 the necessary equipment packages for the gas gathering system were delivered to site and the groundworks completed.   

In 2024, works to convert TE-6 and TE-7 wells from appraisal gas wells into long term gas producers were successfully completed, replacing the carbon steel production tubing with corrosion resistant steel. The wells were opened up in 2025, tested successfully flowing gas with no water.

During 2024, the equipment packages for the gas plant were completed and tested in the workshops, brought from workshops located around the world and delivered to site via the main ports in Morocco. 

In March 2025, the Company announced that the mLNG project main contractor, Italfluid, and the operator of the Tendrara Production Concession had agreed to amend their contractual arrangement by terminating the vendor financed lease agreement entered into in 2020 and entering into an EPC contract. The parties are currently in advanced discussions to agree an operations and maintenance contract. Throughout 2025 the equipment packages are being assembled on site in preparation for plant commissioning and activation in the remaining quarter of the year.

Progress of the Phase 2 Development Project

Based upon current development capital estimates, the funding arising from Managem SA combined with the previously announced project debt financing from Attijariwafa Bank will provide Sound Energy with funds required to achieve first gas under its Phase 2 Tendrara Production Concession development plan. 

Eastern Morocco

Eastern Morocco Licences

Exploration

Our Eastern Morocco Licences comprising the Concession together with the Anoual and Grand Tendrara exploration permits are positioned in a region containing a potential extension of the established petroleum plays of the Algerian Triassic Province and Saharan Hercynian Platform. The presence of the key geological elements of the Algerian Trias Argilo-Gréseux Inférieur or (TAGI) gas play are already proven within the licence areas with the underlying Palaeozoic, representing a significant upside opportunity to be explored.

These licences cover a surface area of over 23,000 square kilometres, but so far only thirteen wells have been drilled, of which six are either located within or local to the Concession. Exploration drilling beyond the region of the Concession has been limited and the Group maintains a portfolio of features identified from previous operators' studies, plus new targets identified by Sound Energy from the recent geophysical data acquisition, subsequent processing and ongoing interpretation studies. These features are internally classified as either prospects, leads or concepts based upon their level of technical maturity and represent potential future exploration drilling targets.

Whilst the Company has strategically prioritised its gas monetisation strategy through the phased development of the TE-5 Horst (Tendrara Production Concession), the Company has also re-evaluated its extensive exploration portfolio within the Grand Tendrara and Anoual exploration permits surrounding the Concession. By integrating the acquired data and learnings from previous drilling campaigns with acquired and reprocessed seismic datasets, the Company has high graded several potential near term subsalt drilling opportunities within the TAGI gas reservoir, the proven reservoir of the TE-5 Horst gas accumulation.

In June 2024, the Company concluded a competitive farm-out process in the under-explored but highly prospective Tendrara Basin in Eastern Morocco. This opportunity provides access to high impact, short term exploration opportunities, in a stable country with very attractive fiscal terms.  By entering into a binding SPA with Managem, the Company has secured the funding of drilling two exploration wells, one on Grand Tendrara and one at Anoual, which each have the potential to be commercialised through the planned infrastructure on Phase 2.  The SPA was completed in December 2024.

 At Grand Tendrara an exploration well is planned on the structure previously drilled by the SBK-1 well in 2000, with an estimated unrisked exploration potential of 140 Bcf gross P_mean Gas Initially in Place (GIIP).  SBK-1 flowed gas to surface during testing in 2000 at a peak rate of 4.41 mmscf/d post acidification but was not tested with mechanical stimulation.  Mechanical stimulation has proven to be a key technology to commercially unlock the potential of the TAGI gas reservoir in the TE-5 Horst gas accumulation and accordingly the Company believes this offers potential to unlock commerciality elsewhere in the basin.

At Anoual a well is planned to be drilled on the M5 prospect located on the Anoual permits, with an estimated unrisked exploration potential of 943 Bcf gross P_mean GIIP. The timing of drilling of both wells are to be agreed with Managem and the Company is providing technical support to the operator on an on-going basis under a Technical Services Agreement.

Southern Morocco

Southern Morocco Licence

Southern Morocco Exploration

The Sidi Moktar licence is located in the Essaouira Basin, in Southern Morocco. The licence covers a combined area of 4,712 km2. The Group views the Sidi Moktar licences as an exciting opportunity to explore high impact prospectivity within the sub-salt Triassic and Palaeozoic plays in the underexplored Essaouira Basin in the West of Morocco.

The Sidi Moktar permit hosts a variety of proven plays. The licence hosts 44 vintage wells drilled between the 1950s and the present day. Previous exploration has been predominantly focused on the shallower post-salt plays. The licence is adjacent to the ONHYM operated Meskala gas and condensate field. The main reservoirs in the field are Triassic aged sands, directly analogous to the deeper exploration plays in the Sidi Moktar licence. The Meskala field and its associated gas processing facility are linked via a pipeline to a state-owned phosphate plant, which produces fertiliser both for domestic and export markets. This pipeline passes across the Sidi Moktar licence. The discovery of the Meskala field proved the existence of a deeper petroleum system in the basin. Specifically, Meskala provides evidence that Triassic clastic reservoirs are effective, proves the existence of the overlying salt seal and gives support for evidence of charge from deep Palaeozoic source rocks. Based on work undertaken by Sound Energy, the main focus of future exploration activity in the licence is expected to be within this deeper play fairway. The Company believes that the deeper, sub-salt Triassic and Palaeozoic plays may contain significant prospective resources, in excess of any discovered volumes in the shallower stratigraphy.

The Company's evaluation of the exploration potential of Sidi Moktar, following an independent technical review, includes a mapped portfolio of sub-salt, Triassic and Palaeozoic leads in a variety of hydrocarbon trap types. Sound Energy is developing a work programme to mature the licence with specific focus on the deeper, sub-salt plays.  The Company believes additional seismic acquisition and processing is required to mature these leads into drillable exploration prospects.

Preparations for this seismic acquisition campaign have commenced with the completion and approval of an Environmental Impact Assessment (EIA) in late 2019.

The Company continues to seek to progress a farm out process for this permit, offering an opportunity to a technically competent partner to acquire a material position in this large tract of prospective acreage. In parallel, the Company continues to engage in dialogue with a number of seismic acquisition and processing contractors for potential services to undertake the survey.

Notes to the Condensed Interim Consolidated Financial Statements

1. Basis of preparation

The condensed interim consolidated financial statements do not represent statutory accounts within the meaning of section 435 of the Companies Act 2006. The financial information for the year ended 31 December 2024 is based on the statutory accounts for the year ended 31 December 2024. Those accounts, upon which the auditors issued an unqualified opinion, have been delivered to the Registrar of Companies and did not contain statements under section 498(2) or (3) of the Companies Act 2006.

The condensed interim financial information is unaudited and has been prepared on the basis of the accounting policies set out in the Group's 2024 statutory accounts and in accordance with IAS 34 Interim Financial Reporting as adopted by the United Kingdom.

The seasonality or cyclicality of operations does not impact on the interim financial statements.

Going concern

As at 31 August 2025, the Group's unaudited cash balance was approximately £2.1 million. The Directors have reviewed the Company's cash flow forecasts for the next 12-month period to September 2026. 

The need for additional financing indicates the existence of a material uncertainty, which may cast significant doubt about the Group and Company's ability to continue as a going concern. These condensed interim consolidated financial statements do not include adjustments that would be required if the Company was unable to continue as a going concern. Mana Energy, the Operator of the Tendrara Production Concession (Concession) expect to achieve first gas before the end of 2025. During August 2025, Mana Energy entered into a facility agreement (subject to some conditions precedent), with a local Moroccan bank to fund Phase 1 of the Concession. The facility is intended to finance capital expenditure, for all the partners, attributable to the engineering, procurement and construction contract with the mLNG project main contractor, Italfuid, during 2025. The Company, through its wholly owned subsidiary, Sound Energy Meridja Limited which has a 20% interest in the Concession, is in discussion with Mana Energy to conclude the terms under which the Company will access up to $5.0 million of the facility to fund its share of the capital expenditure. The Company continues to exercise rigorous cost control to conserve cash resources, and the Directors believe that there are several corporate funding options available to the Company, including various debt, equity and equity-linked funding options. The Directors therefore have a reasonable expectation that the Company and the Group will be able to secure the funding required to continue in operational existence for the foreseeable future and have made a judgement that the Group will continue to realise its assets and discharge its liabilities in the normal course of business. Accordingly, the Directors have adopted the going concern basis in preparing the condensed interim consolidated financial statements.

2. Segment information

The Group categorises its operations into three business segments based on Corporate, Exploration and Appraisal and Development and Production. The Group's Exploration and Appraisal activities are carried out in Morocco. The Group's reportable segments are based on internal reports about the components of the Group which are regularly reviewed by the Board of Directors, being the Chief Operating Decision Maker, for strategic decision making and resources allocation to the segment and to assess its performance. The segment results for the period ended 30 June 2025 are as follows:

3. Profit/(loss) per share

The calculation of basic profit/(loss) per Ordinary Share is based on the profit/(loss) after tax and on the weighted average number of Ordinary Shares in issue during the period. The calculation of diluted profit/(loss) per share is based on the profit/(loss) after tax on the weighted average number of ordinary shares in issue plus weighted average number of shares that would be issued if dilutive options and warrants were converted into shares. Basic and diluted profit/(loss) per share is calculated as follows:

4. Property, plant and equipment

The Company undertook an assessment of external and internal indicators of impairment as at 30 June 2025 and concluded that there was no indication that the carrying amount of the Company's share of the Tendrara Production Concession was impaired.

5. Intangibles

6. Prepayments

During Q1 2025 Micro-LNG Project main contractor, Italfluid, and the operator of the Tendrara Production Concession agreed to amend their contractual arrangement by terminating the vendor financed lease agreement entered into in 2020 and entering into an engineering, procurement and construction (EPC) contract. As a result, amounts previously reported as non-current prepayment were reclassified to property, plant and equipment.                                    

7. Deferred consideration

Deferred consideration relates to future funding to be received by the group from Managem SA, (the purchaser) of the Company's former subsidiary disposed in December 2024. The Company's share of its future expenditure on the Tendrara Production Concession Phase 2 development (Phase 2 development) will be funded by the purchaser up to $24.5 million, the purchaser will also fund the drilling of one exploration well on each of the Anoual and Grand Tendrara licences for up to $2.6 million and $3.6 million, respectively, and pay to the group $1.5 million upon achieving first gas on the Phase 2 development. The Company calculated the deferred consideration after taking account of the expected timing of receipt of the various elements of the deferred consideration based on current estimates of the timing of the operations and applied a discount rate of 10.24% (2024: 10.55%).

8. Cash and cash equivalents

For the purposes of the condensed interim consolidated statement of cash flows, cash and cash equivalents comprise the following as at 30 June 2025.

​

9. Loans and borrowings

The Company has €25.32 million secured bonds (the "Secured Bonds"). The Secured Bonds mature on 21 December 2027. The Secured Bonds bear 2% cash interest paid per annum until maturity and 3% interest per annum to be paid at redemption. In 2021, the Company issued to the Bondholders 99,999,936 warrants to subscribe for new ordinary shares in the Company at an exercise price of 2.75 pence per share. The warrants expire on 21 December 2027. The Bonds are secured on the issued share capital of Sound Energy Morocco South Limited. After taking account of the terms of the Bonds, the effective interest is approximately 6.5%.                                                                                       

The Company has a $18.0 million 6% secured loan note facility with Afriquia Gaz maturing in December 2033 (the ''Loan''). The drawn down principal bears 6% interest per annum payable quarterly, but was deferred and capitalised semi-annually, until the second anniversary of the issue of Notice to Proceed. Repayment of interest that is not deferred commenced in Q2 2024. The principal and deferred interest will be repayable annually in equal instalments commencing December 2028. The Loan is secured on the issued share capital of Sound Energy Meridja Limited. The weighted effective interest on the drawdowns made is approximately 6.2%.

The Company has outstanding interest of £0.6 million accrued on previously issued convertible bonds that were converted to equity and £0.25 million being the principal amount that was then outstanding repaid in December 2024.  The carrying amount of the deferred interest is stated at fair value and is measured using the discounted cashflow method. A discount rate of 17.4% was used to discount the outstanding deferred interest over the term of the liability.

10. Discontinued operations

On 14 June 2024, the Company announced that it had entered into a binding sale and purchase agreement with Managem SA for the disposal of SEME that owns:

·      55% interest in the Tendrara Production Concession, including the liability for payments arising from the Schlumberger net profit interest (NPI) agreement (pursuant to the acquisition of Schlumberger Silk Route Services Limited in 2021);
