[333-269535](https://www.sec.gov/Archives/edgar/data/1939965/000121390023007362/ea172585-s8_brerahold.htm) and [333-287999](https://www.sec.gov/Archives/edgar/data/1939965/000121390025054035/ea0245516-s8_brerahold.htm)), in each case, to the extent not superseded by documents or reports subsequently filed or furnished by the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

**Entry into a Material Definitive Agreement.**

On May 21, 2026, Brera Holdings PLC, a public limited company incorporated in the Republic of Ireland (the "Company"), and certain individual investors (the "Purchasers") entered into a subscription agreement (the "Subscription Agreement"), pursuant to which the Company agreed to sell to such Purchasers an aggregate of 2,298,000 Class B Ordinary Shares, $0.50 nominal value per share (the "Class B Ordinary Shares"), in a registered direct offering (the "Financing").

This Financing is being completed without an underwriter or a placement agent and the Company is not paying underwriting discounts or commissions, so the proceeds to the Company, before expenses, will be approximately $11.4 million. The Company estimate the total expenses of this offering will be approximately $0.05 million.

The Company intends to use the net proceeds from the Financing for working capital and general corporate purposes. The Financing closed on May 27, 2026.

The form of the Subscription Agreement is attached hereto as Exhibit 10.1 and is incorporated herein by reference. The foregoing summary of the terms of the Subscription Agreement is not complete and is qualified in its entirety by reference to such exhibit.

The sale and offering of Class B Ordinary Shares is effected as a takedown off the Company's shelf registration statement on Form F-3 (File No. 333-276870), as amended (the "Shelf Registration Statement"), which became effective on February 13, 2024, pursuant to a prospectus supplement to be filed with the Securities and Exchange Commission on or about the date hereof.

This report on Form 6-K shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;1.2 This legal opinion (this "**Opinion**") is confined to and given
in all respects on the basis of the laws of Ireland (meaning Ireland, exclusive of Northern Ireland) in force as at the date of this Opinion
as currently applied by the courts of Ireland. We have made no investigations of and we express no opinion as to the laws of any other
jurisdiction or the effect thereof. In particular, we express no opinion on the laws of the European Union as they affect any jurisdiction

such laws do not prohibit and are not inconsistent with any of the obligations or rights expressed in the Documents (as defined in paragraph
1.3) or the transactions contemplated thereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the matters expressly stated herein at paragraph 2 below
and is not to be read as extending by implication or otherwise to any other matter;

We express no opinion, and make no representation or warranty, as to any matter of fact or in respect of any documents, which may exist in relation to the Shares, other than the Documents.

&nbsp;&nbsp;&nbsp;&nbsp;1.4 In giving this opinion, we have relied upon the Corporate Certificate (as defined
in the Schedule to this Opinion), the Searches (as defined below) and we give this opinion expressly on the terms that no further investigation
or diligence in respect of any matter referred to in the Corporate Certificate or the Searches is required of us.

&nbsp;&nbsp;&nbsp;&nbsp;1.5 For the purpose of giving this Opinion, we have examined copies sent to us by email

existing under the laws of Ireland and has the requisite corporate authority to issue the Shares.

&nbsp;&nbsp;&nbsp;&nbsp;2.2 When the Shares are allotted and issued pursuant to duly adopted
resolutions of the board of directors of the Company or a committee so appointed by the board of directors, the Shares shall be validly
issued, fully paid or credited as fully paid and non-assessable (which term means that no further sums are required to be paid by the
holders thereof in connection with the issue of the Shares).

![](ea029184901_ex5-1img3.jpg)

3. Assumptions

become effective under the Securities Act;

paid up on the Shares pursuant to their terms of issue;

has expired;

The Investor hereby consents to delivery of the Prospectus in accordance with Rule 172 under the Securities Act.

**6.** The obligations of the Company to issue and sell the Shares to the Investor shall be subject to: (i) the receipt by the Company of the Subscription Amount and (ii) the accuracy of the representations and warranties made by the Investor and the fulfillment of those undertakings of the Investor to be fulfilled prior to the Closing Date.

**7.** The Investor hereby makes the following representations, warranties and covenants to the Company:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)** The Investor represents that (i) it has received or had full access to the Base Prospectus, as well as the Company's periodic reports and other information incorporated by reference therein, prior to or in connection with its receipt of this Agreement, (ii) it is knowledgeable, sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in securities representing an investment decision like that involved in the purchase of the Shares, and (iii) it does not have any agreement or understanding, directly or indirectly, with any person or entity to distribute any of the Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)** The Investor has the requisite power and authority to enter into this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement by the Investor and the consummation by it of the transactions contemplated hereunder have been duly authorized by all necessary action on the part of the Investor. This Agreement has been executed by the Investor and, when delivered in accordance with the terms hereof, will constitute a valid and binding obligation of the Investor enforceable against the Investor in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' and contracting parties' rights generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c)** The Investor understands that nothing in this Agreement or any other materials presented to the Investor in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(d)** The making, execution and performance of this Agreement by the Investor and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under, (i) the charter, bylaws or other organizational documents of such Investor, as applicable, or (ii) any law, order, rule, regulation, writ, injunction, judgment or decree of any court, administrative agency, regulatory body, government or governmental agency or body, domestic or foreign, having jurisdiction over such Investor or its properties, except for any conflict, breach, violation or default which is not reasonably likely to have a material adverse effect on such Investor's performance of its obligations hereunder or the consummation of the transactions contemplated hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(e)** The Investor represents that it is not a, and it has no direct or indirect association with any, FINRA member or an Associated Person (as such term is defined under the FINRA Membership and Registration Rules Section 1011) as of the date hereof.

**8.** Each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement.

**9.** Notwithstanding any investigation made by any party to this Agreement, all covenants, agreements, representations and warranties made by the Company and the Investor herein will survive the execution of this Agreement, the delivery to the Investor of the Shares being purchased and the payment therefor.

**10.** This Agreement may not be modified or amended except pursuant to an instrument in writing signed by the Company and the Investor.

**11.** In case any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein will not in any way be affected or impaired thereby.

**12.** This Agreement will be governed by, and construed in accordance with, the internal laws of the State of New York, without giving effect to the principles of conflicts of law that would require the application of the laws of any other jurisdiction.

**13.** This Agreement may be executed in counterparts, each of which will constitute an original, but all of which, when taken together, will constitute but one instrument, and will become effective when counterparts have been signed by each party hereto and delivered to the other party, and such counterparts may be delivered electronically.

**14.** This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person.

**15.** The Investor acknowledges and agrees that such Investor's receipt of the Company's counterpart to this Agreement shall constitute written confirmation of the Company's sale of Shares to such Investor.
