Credit Suisse AG, acting through its Nassau and London Branches

U.S. Medium-Term Note Program under the Credit Suisse Group AG and Credit Suisse AG U.S. Shelf

Ladies and Gentlemen

We, Homburger AG, have acted as special Swiss counsel to Credit Suisse AG (Credit Suisse), a Swiss bank, in connection with senior medium-term notes (the Notes) to be issued from time to time on or after the date hereof by Credit Suisse, acting through either its Nassau Branch or its London Branch (each, an Issuing Branch), under the Senior Indenture dated as of March 29, 2007 (the Base Indenture), between Credit Suisse and The Bank of New York Mellon, as trustee (in such capacity, the Trustee), as supplemented by the Second Supplemental Indenture dated as of March 25, 2009 (the Second Supplemental Indenture), and the Third Supplemental Indenture dated as of September 9, 2020 (the Third Supplemental Indenture and, together with the Base Indenture and the Second Supplemental Indenture, the Indenture), between Credit Suisse and the Trustee. As such counsel, we have been requested to give our opinion as to certain matters of Swiss law relating to the Notes.

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 the Documents (as defined below), and is not to be read as extending, by implication or otherwise, to any agreement or other document referred to

in any of the Documents (including, in the case of the Prospectus (as defined below), any document incorporated by reference therein or exhibited thereto) or any other matter.

For purposes of this opinion, we have not conducted any due diligence or similar investigation as to factual circumstances that 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 this opinion, we have only reviewed the following documents (collectively, the Documents):

as of May 4, 2015, by and among Credit Suisse, Davis Polk & Wardwell LLP (Davis Polk) and Homburger AG (as amended from time to time, the Agreement About Opinions);

and (E) the power of attorney dated July 22, 2022, issued by D. Mathers, as CFO, and G.M. Martino, as Treasurer (the 2022 Power of Attorney);

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 the laws of Switzerland.

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.

In rendering the opinion below, we have assumed the following:

Based on the foregoing and subject to the qualifications set out below, we are of the opinion that:

The above opinions are subject to the following qualifications:

Save as aforementioned, this opinion may not be transmitted by you to any other person, quoted or referred to in any public document or filed with anyone, in each case, without our express consent.

This opinion is governed by and shall be construed in accordance with the laws of Switzerland.
