Dublin, March 23, 2026 (GLOBE NEWSWIRE) -- Fusion Fuel Green PLC (NASDAQ:HTOO) ("Fusion Fuel" or the "Company"), a leading provider of full-service energy engineering, advisory, and utility solutions, today announced that its Board of Directors has approved the appointment of James Passin to its Board of Directors.

Mr. Passin brings more than 20 years of uranium-focused investing experience to Fusion Fuel's Board and is expected to strengthen the Company's strategic capabilities in connection with its planned acquisition of a controlling interest in Royal Uranium Inc. ("Royal Uranium") and its uranium royalty strategy. Mr. Passin was as one of the earliest professional investors to identify uranium's long-term investment potential, establishing uranium exploration and mining as a core focus in 2000 of Firebird Global Fund, a hedge fund managed by Firebird Management LLC ("Firebird Management"), when prices were below $8 per pound and institutional participation was limited. As a former manager at Firebird Management, Mr. Passin's disciplined, cycle-aware approach was demonstrated by exiting uranium positions ahead of the post-2007 price decline, reflecting a track record of strategic capital allocation across commodity cycles.

Fusion Fuel is seeking to build a capital-efficient uranium royalty platform designed to provide shareholders with exposure to uranium price appreciation, exploration success, project advancement, and potential future production across a diversified portfolio of royalty interests, without taking on the direct capital intensity and operating risks associated with building and operating mines.

Through its planned acquisition of a controlling interest in Royal Uranium, Fusion Fuel is seeking to build a diversified uranium royalty platform with exposure to projects across several attractive jurisdictions, including Canada's Athabasca Basin, one of the world's highest-grade uranium districts. The portfolio includes royalty interests associated with projects operated by established uranium industry participants, including Cameco Corporation, Denison Mines Corp., Orano SA, Uranium Energy Corp., and IsoEnergy Ltd., which Fusion Fuel believes strengthens the quality and long-term potential of the platform.

Mr. Passin is a long-time uranium investor with extensive experience across commodity cycles, resource finance, and frontier-market investing. In 2000, he made uranium exploration and mining a core investment focus at Firebird Global Fund, well before the sector attracted broad institutional attention. During his tenure at Firebird Management, he directed and managed a resource portfolio in excess of $1 billion, with significant experience in early-stage resource companies across the Americas, Central Asia, Africa, and other frontier and emerging markets.

Why the Royalty Model Matters

Fusion Fuel's uranium royalty strategy is intended to offer investors a different way to participate in the uranium market than traditional mining ownership. Rather than funding exploration programs, mine construction, sustaining capital, or day-to-day operations, a royalty holder is generally positioned to benefit from project advancement and potential future production while the operator bears the direct development and operating costs of the underlying asset.

As a result, the royalty model can provide a more capital-efficient form of uranium exposure, with potential upside to:

rising uranium prices,
exploration success and resource expansion,
project derisking and development milestones, and
future production growth across underlying royalty-bearing assets.

At the same time, the model is intended to reduce direct exposure to many of the risks that typically weigh on mining operators, including construction delays, capital cost overruns, operating cost inflation, and day-to-day execution risk.

Fusion Fuel believes this structure is particularly attractive in the current uranium environment, where long-term fundamentals continue to strengthen as energy security concerns, the growing role of nuclear power, and rising electricity demand from data centers and artificial intelligence infrastructure support renewed focus on uranium supply.

The Company's planned acquisition of a controlling interest in Royal Uranium is expected to add a diversified uranium royalty portfolio with exposure to projects in premier jurisdictions and with established industry operators, positioning Fusion Fuel to participate in uranium sector upside through a scalable royalty platform.

"James brings exactly the kind of uranium-market experience and cycle-tested judgment that we believe is valuable as Fusion Fuel pursues its uranium royalty strategy," said JP Backwell, Chief Executive Officer of Fusion Fuel. "He has spent more than two decades evaluating uranium opportunities across multiple cycles and understands both the strategic appeal of the sector and the importance of disciplined capital allocation. As we continue building our uranium royalty platform, we believe his perspective will be highly valuable to our Board and our shareholders."

"Fusion Fuel is pursuing a strategy that I believe is highly relevant to the current uranium market," said James Passin. "Uranium royalties can provide attractive exposure to uranium price appreciation and project upside without the direct capital intensity and operating risks of mine ownership. With an anticipated diversified royalty portfolio spanning several important jurisdictions, including exposure to the Athabasca Basin, Fusion Fuel would be positioned to participate in the sector through a model that could offer meaningful upside with a more disciplined risk profile. I look forward to supporting the Company as it seeks to advance that strategy."
