• The Company generated approximately €6.9 million in revenue during the six months ended June 30, 2025, compared to no revenue during the same period of the prior year, primarily due to its acquisition of the liquified petroleum gas ("LPG") engineering and distribution operations of Quality Industrial Corp. in November 2024.
• The Company reported an operating loss of approximately €2.9 million for the six months ended June 30, 2025, compared to approximately €7.9 million for the six months ended June 30, 2024, driven by the Company's reduction of loss-making operations.
• The Company held its annual general meeting, at which it obtained shareholder approval for all of the Company's proposals.
• The Company gained an extension to regain compliance with certain Nasdaq listing rules and transferred its publicly-traded securities to The Nasdaq Capital Market tier of The Nasdaq Stock Market LLC ("Nasdaq"), allowing the Company to regain compliance with all applicable Nasdaq Listing Rules after the end of the period ended June 30, 2025.
• Fusion Fuel established Bright Hydrogen Solutions Ltd ("BrightHy Solutions"), a wholly owned subsidiary, as the Company's relaunched hydrogen solutions platform, offering engineering advisory, equipment sourcing, and project oversight services.

• Fusion Fuel signed non-binding heads of terms to acquire a United Kingdom fuel distribution company, which, subject to negotiation of definitive agreements, would further expand the Company's energy portfolio.

"Over the first six months of 2025, we continued to make progress toward regaining compliance with all applicable Nasdaq Listing Rules, which we subsequently obtained, as announced in August 2025. Moreover, we reported approximately €6.9 million in revenue in the first half of 2025 compared to none during the same period in 2024, and reported operating costs during the first six months of 2025 that were 64% lower than during the prior year's first six-month period," said John-Paul Backwell, CEO of Fusion Fuel. "We have demonstrated both strong operational progress and a significant turnaround."
