Half-year Results

Powerhouse Energy Group plc (AIM: PHE), the UK technology company pioneering integrated technology that converts non-recyclable waste into low carbon energy together with a revenue generating engineering consulting division (Engsolve), is pleased to announce its unaudited half year report for the six months ended 30 June 2025.

Highlights

Corporate

• Business strategy remains focused on licensing fees, royalties and engineering services revenues which include potentially providing third party testing of waste streams at the Powerhouse Technology Centre once fully commissioned.
• Powerhouse has decided to raise project finance, in respect of its Ballymena project, although it must be stressed at this time this remains an exception and is due to the Company's favourable assessment of the project's commercial risk. We have opportunities for Project funding and as Ballymena has the necessary commercial criteria, feedstock offtake, local authority support etc to allow Powerhouse to seek project funding that will give us greater project control and allow the project to be delivered in a more favourable timescale for the business.

Commercial Development

• Continuing to progress projects with Australian based National Hydrogen Limited (NH2) with the FEED being completed.
• The Ballymena, NI project continues to progress - PHE now await completion of legal documentation pertaining to the lease for the site.
• The JV with Hydrogen Utopia at Longford has been dissolved following the project having lost the prospective land option.
• Engsolve H1's performance has been strong with orders exceeding expectations.
• Continuing to work with Altec Energy, in Thailand, with PHE providing support in the form of time to enable Altec to deliver its strategy and develop early stage enquiries.
• The previously agreed option agreement on the plot at Protos has not been renewed.
• A significant number of qualified leads are being followed up following the successful launch of the Company's Feedstock Testing Unit, with a number of client visits completed as well as successful tests on client waste undertaken.
• The Company continues to investigate grant funding as a way of reducing our time to commercialisation and is in the process of submitting appropriate applications.

Technology and Innovation

• Feedstock Testing Unit (FTU) completed with test results successfully verifying a number of waste streams, including specific wastes for interested parties. Further optimisation achieved from learnings on running the FTU, which will improve the efficiency and commerciality of the DMG offering.
• Further patents granted in Indonesia, USA, Australia, and Europe.

Financial Performance

• Revenues for the half year of £474.9k (H1 2024: £385.7k).
• Gross Profit for period £166.2k (H1 2024: £98.2k).
• £1.47m cash at bank at 30 June 2025 (30 June 2024: £2.73m).

The Group's revenues for the half year ended 30 June 2025 increased compared to the previous year's figures due to the additional sales orders Engsolve received in the first half of 2025.

Fundraise

· In March 2025 the Directors took the decision to raise additional working capital in preparation for projects such as Ballymena and NH2 gathering momentum thus avoiding the potential distraction of the executive team being required to raise capital at the same time as delivering time and revenue critical projects, and to facilitate the acceleration in the Research and Development activities of the Company (to demonstrate the flexibility of the DMG process at the Company's Technology Centre in Bridgend and to build a proactive marketing strategy that is able to build system awareness and as result a continuous pipeline of opportunities).

• A placing of 250,000,000 Ordinary Shares and a retail offering of 25,000,000 Ordinary Shares raised total gross proceeds of approximately £1.375 million in aggregate for the Company.

Outlook

• Completion of the FTU is enabling the Company to accelerate the development of commercial applications for its technology through site visits and interest in providing waste testing.
• Further innovation and product offerings are being developed. Including a proposal to provide gasification technology into the Sustainable Aviation Fuel ("SAF") arena.
• In order to increase awareness and drive further revenue, Engsolve has engaged an experienced industrial sales originator to identify new client and project opportunities.

Statement from David Hitchcock, Non-Executive Chairman of Powerhouse Energy Group Plc

"PHE started 2025 with continued momentum. Our business strategy continues to play to the Company's strengths with our strong knowledgeable executive team, and the most consistent and stable board the business has had, committed to growing the business.

In line with our stringent cost management and qualified project spend only, we have closed off the Protos and Longford projects as they are no longer commercially viable for reason of cost or non-availability of land respectively.

We have a significantly increasing pipeline of potential opportunities that our CEO Paul Emmitt and CFO Ben Brier are progressing in line with our commercial validation process with a view to advancing them whilst minimising any costs incurred to Powerhouse. Our Engsolve team has also been very active delivering a very strong order book in H1 which continues to contribute greatly to the Group, bringing new revenue streams into the Company whilst providing support to PHE and its strategy.

The final commissioning of the FTU at the Powerhouse Technology Centre was a major milestone for the Company. This has rapidly become the cornerstone in PHE's ability to further advance as well as promote its technology and expertise. The Centre will undoubtedly also help to support the Company's investments in our capital projects in Northern Ireland. We are also very pleased with the considerable interest being expressed in PHE's offering in south-east Asia and Australia and look forward to progressing these opportunities. We were also delighted with the progress that has been made on patent applications / resolutions, further validating the engineering work that has been undertaken into getting the Company to this point as we drive towards commerciality.

The second half of the year promises to be another exciting one for PHE as we look forward to advancing the projects from our pipeline of opportunities whilst further maximising the benefits of having a fully operational technology centre which we believe will undoubtedly help provide even greater impetus to our pipeline whilst further innovating the services that we can provide customers.

I would like to take this opportunity to thank all our stakeholders for their continued support and look forward to providing further updates in due course."

Summary of significant accounting policies

The following accounting policies have been applied consistently in dealing with items which are considered material in relation to the financial information.

1.1. Basis of preparation

This half year consolidated financial information is for the six months ended 30 June 2025 and has been prepared in accordance with International Accounting Standard 34 "Interim Financial Statements". The accounting policies applied are consistent with International Financial Reporting Standards ("IFRS") issued by the International Accounting Standards Board (IASB) as adopted for use in the United Kingdom and with those parts of the Companies Act 2006 applicable to companies reporting under IFRS (except as otherwise stated). The accounting policies and methods of computation used in the half year financial information are consistent with those of the previous financial year and corresponding half year reporting period.

The Group does not consider any new and amended standards that became applicable for the current reporting period to have any impact on the Groups results.

The unaudited results for period ended 30 June 2025 do not constitute statutory accounts within the meaning of Section 435 of the Companies Act 2006. The comparative figures for the period ended 31 December 2024 for the Company are extracted from the audited financial statements which contained an unqualified audit report and did not contain statements under Sections 498 to 502 of the Companies Act 2006.

This half year financial statement will be, in accordance with the AIM Rules for Companies, available shortly on the Company's website.

1.2. Going concern

The Directors have considered all available information about future events when considering going concern. The Directors have prepared and reviewed cash flow forecasts for 12 months following the date of these Financial Statements. The projections show that the Group will have sufficient funding to be able to continue as a going concern on the basis of its cash balances as at 30 June 2025.

The half year financial statements do not include the adjustments that would result if the Group were unable to continue as a going concern.

1.3. Functional and presentational currency

This half year financial information is presented in £ sterling which is the Group's functional currency.

1.4. Fixed asset investments

Interests in subsidiaries, associates and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses. The investments are assessed for impairment at each reporting date and any impairment losses or reversals of impairment losses are recognised immediately in the profit and loss account.

1.5. Revenue

The Group provides engineering services for the application of the DMG technology, the intellectual property that the Group owns. Revenue from providing services is recognised in the accounting period in which services are rendered. For fixed-price contracts, revenue is recognised based on the actual service provided to the end of the reporting period as a proportion of the total services to be provided to the extent to which the customer receives the benefits. This is determined based on the actual labour hours spent relative to the total expected labour hours.

Where a contract includes multiple performance obligations as specified by the work scope, the transaction price will be allocated to each performance obligation based on the estimated expected cost-plus margin.

In the case of fixed-price contracts, the customer pays the fixed amount based on a payment schedule. If the services rendered by the Group exceed the payment, a contract asset is recognised. If the payments exceed the services rendered, a contact liability is recognised.

SHARE CAPITAL

The deferred shares have no voting rights and do not carry any entitlement to attend general meetings of the Company. They carry only a right to participate in any return of capital once an amount of £100 has been paid in respect of each ordinary share. The Company is authorised at any time to effect a transfer of the deferred shares without reference to the holders thereof and for no consideration.
