Richard Scott, CEO of CPH2, commented: “The first half of 2026 was a period of significant progress, followed by a significant setback which prompted an important and decisive change in strategy with new leadership. With the successful, oversubscribed fundraise and the restructure of the Company now completed, we are in a strong position with significantly reduced cash burn going forward.

The reset has allowed us to reposition the Company towards more attractive capital-light model and the flexibility to enter higher growth global markets, better aligned with our core strengths and capabilities.

The Group's strategic objective is to deliver the lowest lifetime LCOH in the market in relation to the production of hydrogen for the growing electrolysis or decentralised markets and alternative energy markets. CPH2 is listed on the AIM market and trades under the ticker AIM:CPH2. For more information: Chief Executive’s Statement I’m pleased to report to shareholders as the new Chief Executive of the Company. CPH2 has a wealth of advanced technical capability, experience and significant intellectual property across hydrogen related technologies.

I am excited for the future of the Company as we rapidly execute a capital-light model to leverage our core strengths in the still growing global market for hydrogen production. Commercially, the first half of 2026 was characterised by strong growth in commercial traction, building relationships with parties capable of supporting the next phase of commercial development. Formal engagement commenced with Siemens to support product and process development, customer introductions and go-to-market strategies.

In addition, the Company announced non-binding MoUs with Koch Modular Process Systems LLC and ABE Gruppe GmbH to explore manufacturing, licensing, supply, installation and servicing opportunities in targeted international markets. The Company continued progress during the period with major technical and regulatory milestones passed. This was followed by a material delay in our innovation programme due to the incident on 28 May 2026.

As previously reported, the Company’s initial investigations established that the Group’s proprietary membrane-free stack and associated separators were not the cause of the incident, and the Company has engaged an independent consultant to define the root cause, which will provide a basis for determining the technology product roadmap. These independent reports have not yet been submitted to the Board on the agreed timescales. We will provide an update on the conclusions once they have been received and reviewed. Detailed internal technical analysis, now completed, does not alter our previous view or statements.

We expect the external and independent report to be materially similar. Following the incident, the Company swiftly undertook a strategic pivot towards a more capital-light model focused on technology development, intellectual property exploitation and global licensing, and appointed new leadership to drive the business forward in a new direction. The existing three licensees across 14 countries remain an important foundation for the Company’s revised commercial model, and we are encouraged that the licensees have continued to support the business following the testing incident.

As announced, CPH2 entered into a binding term sheet with Hidrigin which included a £750k convertible loan (subject to final negotiation and definitive agreement), and an exclusivity arrangement to negotiate and complete a Strategic Partnership and Manufacturing and Technology Development Agreement. The new strategy focuses on CPH2’s core strengths of electrolyser and hydrogen technology design and innovation. Now being unconstrained by internal manufacturing limitations, CPH2 can target new, higher growth market opportunities such as Sustainable Aviation Fuels (SAF) and Ammonia which both have a hydrogen requirement.

This is typically in very large volumes, and our technology can play a part. The new market for UAVs (drones) is via Defence contractors who value the range, thermal and noise advantages of hydrogen. We are developing a revised product roadmap to better capture these opportunities, and to leverage not only the exceptional technology progress made in 2025, but also our proven capabilities in developing electrolyser systems providing premium-price ultra-high purity hydrogen and oxygen for markets such as semiconductors, pharmaceuticals, solar cell manufacturing and water treatment.

Financial review The period to 30 June 2026 comprised of a strong focus on correct capital allocation to facilitate CPH2 achieving its key milestones, while keeping tight control of expenditure over other activities. 4m). 2m higher than the comparative period. 6m).

1m) following the Company’s strategic decision not to continue manufacturing. The contract in question has since been settled and no further obligations arise in relation to the contract. Following the incident on 28 May 2026, a dedicated effort has been made to restructure and significantly reduce costs to achieve a substantially lower cash burn going forward as part of its transition to a capital-light licensing model.

3m gross proceeds, placing the Company in a secure financial position and together with the accelerated restructuring and repositioning program, which is now complete, CPH2 is well-positioned to capitalise on its valuable intellectual property portfolio in a more sustainable, faster to market, lower cost manner. Conclusion and Outlook The Board has moved quickly to reposition CPH2 as a capital-light technology development and licensing business. The reset has allowed us to reorient towards new target markets unencumbered by legacy decisions and to strive towards opportunities which better reflect the Company’s core strengths.

Cash burn is on track to be down 70% in Q1 2027 v Q1 2026 and we retain our existing licensees in challenging circumstances. We are progressing to expand licensing routes globally and develop new technologies to meet the needs of a rapidly evolving market opportunity. We look forward to sharing a new product and technology roadmap in the coming months. I would like to thank our employees, shareholders, partners and licensees for their continued support during this period of transition.

CPH2 has valuable intellectual property, a committed highly knowledgeable team and a more focused route to market. We believe the strategic pivot provides the right platform from which to pursue the significant commercial opportunities available to the Company and to create long-term value for shareholders. 80) The accompanying notes are an integral part of these condensed consolidated financial statements.
