On
December 31, 2025, Fusion Fuel Green PLC, an Irish public limited company (the “Company”), entered into a supplement to letter
agreement (the “BPLLC Engagement Letter Supplement”) with Bevilacqua PLLC, the Company’s outside securities counsel
(“BPLLC”). The BPLLC Engagement Letter Supplement amended and supplemented that certain engagement agreement, dated October
30, 2024, between BPLLC and the Company. Under the BPLLC Engagement Letter Supplement, the Company agreed that the Company was obligated
to pay BPLLC $395,502.28 for services rendered to the Company through November 30, 2025 by BPLLC (the “Outstanding Fees”).
The BPLLC Engagement Letter Supplement provided that BPLLC agreed to deduct $200,000 from the Outstanding Fees, provided that on the
date of the BPLLC Engagement Letter Supplement, the Company issued BPLLC a five-year warrant (the “BPLLC Warrant”) to purchase
an aggregate of 71,429 Class A ordinary shares of the Company with a nominal value of $0.0035 each (“Class A Ordinary Shares”).
The
BPLLC Warrant has an exercise price of $0.88 per share and provides for demand registration rights with respect to the Class A Ordinary
Shares issuable upon exercise of the BPLLC Warrant (the “Warrant Shares”). In addition, the Company and BPLLC agreed to a
volume cap on dispositions of the Warrant Shares, pursuant to which the holder of the BPLLC Warrant may not sell, transfer, or otherwise
dispose of Warrant Shares on any trading day if such disposition would cause the holder’s total sales of Class A Ordinary Shares
to exceed 10% of that day’s aggregate trading volume on the Company’s primary trading market.
The
Company’s Chief Executive Officer, John-Paul Backwell, stated: “This agreement is part of our effort to reduce the burden
on the Company’s cash balance with a close partner.”
The
BPLLC Warrant and the BPLLC Engagement Letter Supplement are furnished as Exhibit 4.1 and Exhibit 10.1 to this Report on Form 6-K,
respectively, and the description above is qualified in its entirety by reference to the full text of such exhibits.
