Ladies and Gentlemen

We, Niederer Kraft Frey Ltd, have acted as special Swiss counsel to Sportradar Group AG, a stock corporation incorporated under the laws of Switzerland (the “Company”), in connection with the filing of a registration statement on Form F-1, including the prospectus set forth therein (the “Registration Statement”), to be filed with the United States Securities and Exchange Commission (the “SEC”) on the date hereof for the purpose of registering under the United States Securities Act of 1933, as amended (the “Securities Act”), the offer and sale of newly issued Class A ordinary shares of the Company, each with a nominal value of CHF 0.10 (the “Class A Ordinary Shares”), including any Class A Ordinary Shares with a nominal value of CHF 0.10 each to be sold, if and to the extent such option is exercised, to the underwriters pursuant to the over-allotment option granted by the Company to the underwriters. In our capacity as special Swiss counsel to the Company, we have been requested to render an opinion as to certain Swiss legal matters.

1.	Basis of Opinion

This opinion is confined to and given on the basis of the laws of Switzerland in force at the date hereof. Such laws and the interpretation thereof are subject to change. In the absence of explicit statutory law, we base our opinion solely on our independent professional judgment. This opinion is also confined to the matters stated herein, and is not to be read as extending, by implication or otherwise, to any agreement or document referred to in any of the Documents (as defined below) or any other matter.

For purposes of this opinion we have not conducted any due diligence or similar investigation as to factual circumstances, which are or may be referred to in the Documents, and we express no opinion as to the accuracy of representations and warranties of facts set out in the Documents or the factual background assumed therein.

For purposes of rendering this opinion, we have only examined and relied on originals or copies of the following documents available to us (collectively the “Documents”):

i.	an electronic copy of the Registration Statement; and

ii.	an electronic copy of the articles of association (Statuten) of the Company, the form of which is filed as Exhibit 3.1 to the Registration Statement (the “Articles of Association”).

No documents have been reviewed by us in connection with this opinion other than the Documents. Accordingly, we shall limit our opinion to the Documents and their legal implications under Swiss law.

In this opinion, Swiss legal concepts are expressed in English terms and not in their original language. These concepts may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions. With respect to Documents governed by laws other than the laws of Switzerland, for purposes of this opinion we have relied on the plain meaning of the words and expressions contained therein without regard to any import they may have under the relevant governing law.

3.	Opinion

Based upon the foregoing, in reliance thereon, and subject to the limitations and assumptions referred to above (2.) and the qualifications set out below (4.), we are of the opinion that the Class A Ordinary Shares, when issued and paid for pursuant to the Articles of Association and Swiss law, in particular upon registration of the corresponding share capital increase into the Commercial Register of the Canton of St. Gallen will be validly issued, fully paid as to their nominal value and non-assessable (i.e., no further contributions in respect thereof will be required to be made to the Company by the holders thereof, by the sole reason of their being a holder of Class A Ordinary Shares).

4.	Qualifications

The above opinions are subject to the following qualifications:

The lawyers of our firm are members of the Zurich bar and do not hold themselves out to be experts in any laws other than the laws of Switzerland. Accordingly, we are opining herein as to Swiss law only and we express no opinion with respect to the applicability or the effect of the laws of any other jurisdiction to or on the matters covered herein.

The exercise of voting rights and rights related thereto with respect to any Class A Ordinary Shares is only permissible after registration in the Company’s share register as a shareholder with voting rights in accordance with the provisions of, and subject to the limitations provided in, the Articles of Association.

We express no opinion as to whether the Registration Statement is accurate, true, correct, complete or not misleading. In particular, and without limitation to the foregoing, we express no opinion on whether the Registration Statement provides sufficient information for investors to reach an informed assessment of the Company, any companies within the Company’s consolidation perimeter and the Class A Ordinary Shares.

Notwithstanding or irrespective of registration of the capital increase with the Commercial Register of the Canton of St. Gallen, the underlying shareholders’ resolutions may be challenged by a dissenting shareholder of the Company or others in court or otherwise. Therefore, notwithstanding registration of the Class A Ordinary Shares with the Commercial Register of the Canton of St. Gallen, any shareholder may challenge the resolutions taken by the general meeting of shareholders of the Company on which such registration of the Class A Ordinary Shares with the Commercial Register of the Canton of St. Gallen may be based.

e.	We express no opinion as to regulatory matters or as to any commercial, accounting, calculating, auditing or other non-legal matter. We express no opinion as to tax matters.

f.	We express no opinion as regards compliance with Swiss law and the Articles of Association of the withdrawal of the pre-emptive rights (Bezugsrechte) of the Company’s shareholder in connection with the issuance of the Class A Ordinary Shares.

g.	We express no opinion on the issuance of other shares than the Class A Ordinary Shares.
