Solmate Infrastructure (Brera Holdings, PLC,NASDAQ: SLMT)

Announces Strategic Partnership with Abu Dhabi FinanceWeek 2025

Abu Dhabi, UAE and Dublin, Ireland, November 20, 2025 – Solmate Infrastructure (NASDAQ: SLMT**)** (“Solmate,” “the Company”), the Abu Dhabi-based Solana infrastructure company, today announced that the Company will serve as an official Strategic Partner of Abu Dhabi Finance Week (ADFW), taking place 8–11 December 2025.

Abu Dhabi Finance Week 2025 is the Middle East's premier financial and investment summit, gathering over 20,000 participants, 1,000+ institutional investors, and 500+ speakers to shape the future of finance under the theme “Capital of Capital: Powering the Future of Finance.”

The agreement underscores Solmate’s growing leadership in Middle East blockchain infrastructure and its commitment to deliver blockchain-based solutions aligned with the region's digital transformation agenda. Solmate recently launched the first-ever bare metal Solana validator in the UAE, which is the first performant Solana validator in the Middle East and expected to rank among the top Solana validators globally.

At the Summit, Solmate CEO Marco Santori will deliver a keynote address outlining the company’s current and future plans to support Abu Dhabi’s position as the leader in digital asset infrastructure. The keynote will take place on December 10, 2025.

Marco Santori, Chief Executive Officer of Solmate Infrastructure, commented:

“Abu Dhabi is rapidly establishing itself as the global capital for the digital age. Partnering with ADFW at the strategic level gives us the perfect platform to showcase how Solana’s high-performance infrastructure, combined with real-world institutional-grade treasury and staking solutions, is accelerating the convergence of traditional and decentralized finance. We’re proud to stand shoulder-to-shoulder with ADGM as we build the financial rails of tomorrow — right here in the UAE.”

Exhibit 99.2

Dear Investors,

This is Marco Santori, CEO of Brera Holdings PLC (NASDAQ: SLMT) – soon to be Solmate. Following yesterday's resale registration filing for PIPE shares, the price of our stock dropped meaningfully. This is expected behavior in thinly-traded, low-float stocks and likely reflects investor concerns over additional shares entering the market. It is not unusual to see significant swings in price in these circumstances, particularly for treasury companies, which frequently experience similar phenomena. We don’t think this has anything to do with fundamentals. In any event, what comes after the filing is more important.

As a team, we remain laser-focused on our growth strategy. We have a robust roadmap ahead of us that we are confident will drive SOL-per-share growth over the near term and the long term. Additionally, we expect to report and optimize for something other treasuries have largely ignored: Earnings.

Here is an update on where we stand today as a company:

●	Unlike other treasury companies, we have taken a measured approach to buying SOL, opportunistically acquiring SOL on dips in the market.<br>We didn’t spend all of your PIPE dollars to purchase SOL at the top of the market. We bought the dips and kept some cash to spare.
●	Ark Invest ETFs purchased significant SLMT shares in the open market in addition to their PIPE<br> shares. Ark continues to own a significant portion of the company - over 11% at last measure.
---	---
●	We secured $50 million in SOL at a 15% discount from the Solana Foundation in October. We expect to remain a long-term partner for<br>them in the UAE.
---	---
●	In partnership with RockawayX, we have launched the region's first performant, bare-metal Solana<br> validator. It is already generating revenue.
---	---

Looking ahead, we remain well positioned:

●	We have a strong liquidity position with tens of millions in cash, ready to buy dips and expand operations. We didn’t buy the<br>top; we have a meaningful amount of our powder dry and ready.
●	We continue to pursue our previously announced acquisition strategy and continue to evaluate accretive, synergistic potential targets.
---	---
●	We have secured a strategic partnership with Abu Dhabi Global Markets for Abu Dhabi Finance Week. I will be giving a keynote presentation<br>in front of the plenary assembly on December 10.
---	---
●	Differentiated revenue sources are coming into focus: We are already accepting inbound interest in both delegating to our validator<br>and colocating with it.
---	---

We will stake our SOL, deploy it in DeFi, run trading strategies with it… all the same things that your typical DAT does to earn yield. But we will go beyond yield to generate additional sources of revenue. In partnership with RockawayX, one of our anchor investors, we’ve stood up a performant, bare-metal validator that allows us to offer real infrastructure services like RPC and colocation. These services won’t just generate more SOL, they’ll generate cash - real revenue that we believe will take us out of being evaluated based on mNAV and into earnings multiples.

We didn’t raise your money to run a perpetual motion machine with our stock. We raised it to build the defining Solana infrastructure company in the public markets. Stock price will always be important, but we are keenly focused on execution, and we are just getting started. If you’re in this for the long term – and I believe you are – then we want you along with us on this journey.

Pursuant to the Registration Rights Agreement (the “RegistrationRights Agreement”) dated September 23, 2025, between you and Brera Holdings PLC (the “Company”), the Registration Statement(as defined in the Registration Rights Agreement) for the resale of your Registrable Securities (as defined in the Registration RightsAgreement) was filed with the United States Securities and Exchange Commission on November 19, 2025, and became effective upon filing.For information about how to transfer your shares, please contact the Company’s transfer agent, Equiniti, at 800-468-9716.
