FusionFuel Green PLC Investor Presentation on First Half 2025 and Recent Developments


Dublin, Ireland - September 17, 2025 - Fusion Fuel Green PLC (“Fusion Fuel” or the “Company”) (NASDAQ: HTOO), an integrated energy platform providing LPG distribution and hydrogen solutions, today provided a summary and presentation of its financial results for the first half of 2025, along with updates on its operational performance and strategic initiatives.

2025First Half and Recent Developments


Revenue:<br> The Company generated approximately €6.9 million in revenue during the six months ended<br> June 30, 2025, compared to no revenue during the same period of the prior year, primarily<br> due to its acquisition of the liquified petroleum gas (“LPG”) engineering and<br> distribution operations of Quality Industrial Corp. (“QIND”), the Company’s<br> majority-owned subsidiary, in November 2024.
Operating and Net Loss: The Company reported an operating loss of approximately €2.9 million<br> (with a net loss of approximately €2.3 million attributable to Fusion Fuel shareholders)<br> for the six months ended June 30, 2025, compared to approximately €7.9 million of operating<br> and net loss for the six months ended June 30, 2024, driven by the Company’s reduction<br> of loss-making operations.
--- ---
Balance Sheet: Over $8 million raised year-to-date, which supported the repayment and extinguishment<br> of approximately €4.3 million of debt in July and August 2025, further strengthening<br> the Company’s balance sheet since the first half of 2025.
--- ---
Capital Structure: The conversion of substantially all outstanding convertible notes, combined<br> with the recent equity raises, simplified the Company’s capital structure by reducing<br> legacy instruments and increasing transparency for shareholders.
--- ---
Nasdaq Compliance: During Q3 2025, the Company resolved all outstanding listing deficiencies<br> pursuant to notices received from the staff of The Nasdaq Stock Market LLC (“Nasdaq”),<br> including minimum bid price, shareholder equity, and annual meeting requirements. Following<br> a 1-for-35 share consolidation and the recent capital raises, Fusion Fuel regained full compliance<br> with Nasdaq listing requirements.
--- ---

Operationaland Strategic Progress


Bright Hydrogen Solutions Ltd (“BrightHy Solutions”) advanced its hydrogen platform with new agent agreements, successful tenders to advance to final contract negotiations for two hydrogen projects, and continued progress on the establishment of a €30 million joint venture investment vehicle. The joint venture vehicle is intended to finance mid-scale hydrogen plants in Europe with related offtake agreements, enabling BrightHy Solutions to both deliver technical solutions and act as a project partner. These initiatives are expected to begin contributing to revenues in late 2025, subject to definitive agreements and closing conditions, with additional growth anticipated as the pipeline matures.

Al<br> Shola Al Modea Gas Distribution LLC (“Al Shola Gas”), the Company’s indirect<br> majority-owned subsidiary, continued to deliver strong growth and margin performance. During<br> the six months ended June 30, 2025, the business signed new engineering contracts for approximately<br> $4.5 million in expected revenue and annual fuel supply agreements for approximately $1.7<br> million in expected recurring revenue, while also expanding its fuel truck fleet. With an<br> 18-month backlog of contracted engineering work and bulk supply operations that consistently<br> generate margins above 40%, Al Shola Gas is expected to provide predictable cash flow and<br> remain a key part of the Company’s shift toward profitability.
M&A<br> activity progressed with the signing of Heads of Terms for the acquisition of a UK-based<br> fuel distribution company, which generated approximately $50 million in annual revenue and<br> $12 million in net income during its fiscal year ended April 30, 2025, subject to the execution<br> of definitive agreements and customary closing conditions. Additionally, the Head of Terms<br> for a 51% joint venture was signed to develop a biomass-powered steam project in South Africa<br> subject to the execution of definitive agreements and customary closing conditions. Both<br> transactions are expected to diversify the Company’s revenues and expand its international<br> footprint.

“2025 has been the most important period in our company’s history,” said John-Paul Backwell, Chief Executive Officer of Fusion Fuel. “We have achieved the turnaround that was needed and are quickly moving towards profitable, scalable growth across the energy sector.”

Outlook


The Company provided its full-year 2025 revenue guidance of approximately €17.4 million, representing growth of 70% versus QIND 2024 results, and expects further operational progress across both BrightHy Solutions and Al Shola Gas in the second half of the year.
