Press Release and Term Sheet

On December 4, 2025, Brera Holdings PLC, operating
under the name Solmate Infrastructure (the “Company”) (NASDAQ: SLMT), a Solana-based crypto infrastructure company, issued
a press release announcing the Company has entered into a non-binding term sheet (the “Term Sheet”) with RockawayX Holding
a.s. (the “Seller”) for the proposed acquisition of RockawayX a.s. (“RockawayX” and such transaction, the “Transaction”).

Based upon the terms outlined in the Term Sheet,
upon the closing of the Transaction, the Company would acquire RockawayX for initial consideration of 25 million Class B ordinary shares
of the Company, nominal value $0.05 per share, (the “Class B Ordinary Shares”), and contingent equity earn-out consideration
of up to approximately 62 million additional Class B Ordinary Shares based on the average daily volume weighted average price of the Class
B Ordinary Shares for specified periods during the five-year period following the closing, with earn-out milestones set between $9.00
per share and up to and including $50.00 per share. The Term Sheet also provides that if the average daily volume weighted average price
of the Class B Ordinary Shares for specified periods in the year following signing of the Term Sheet, is at or below a specified price,
the Seller will receive up to an additional 20 million Class B Ordinary Shares in the aggregate, which would offset share-for-share any
contingent equity
