SOPHiA GENETICS SA – Registration Statement on Form S-8

Ladies and Gentlemen

We have acted as special Swiss counsel to SOPHiA GENETICS SA, a stock corporation incorporated under the laws of Switzerland (the Company), in connection with the filing of a registration statement on Form S-8 (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), 3,758,700 ordinary shares of the Company, each with a nominal value of CHF 0.05 (the Ordinary Shares). As such counsel, we have been requested to give our opinion as to certain legal matters of Swiss law.

Capitalized terms used but not defined herein shall have the meaning ascribed to them in the Documents (as defined below).

I. 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 document referred to in the Documents (other than listed 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 this opinion, we have only reviewed originals or copies of the following documents we have deemed necessary or advisable for the purpose of rendering this opinion (collectively the Documents):

(i) an electronic copy of the Registration Statement;

(ii) an electronic copy of the Incentive Stock Option Plan dated September 2013 (the 2013 ISOP);

(iii) an electronic copy of the 2019 Incentive Stock Option Plan in its version of April 22, 2021 (the 2019 ISOP, and together with the 2013 ISOP, the ISOPs);

(iv) an electronic copy of the minutes of a resolution of the board of directors of the Company dated December 5, 2013, approving, inter alia, the 2013 ISOP;

(v) an electronic copy of the minutes of a resolution of the board of directors of the Company dated March 6, 2019, approving, inter alia, the 2019 ISOP;

(vi) an electronic copy of the minutes of a resolution of the board of directors of the Company dated April 22, 2021, approving, inter alia, the amended version of the 2019 ISOP;

(the documents (iv), (v) and (vi) collectively, the Board Resolutions);

(vii) electronic copies of the notarized and non-notarized minutes of the Company's extraordinary general meeting held on June 29, 2021 (the Shareholders' Resolution), resolving on, inter alia, contingent upon the completion of the initial public offering of the shares on the Nasdaq Stock Market (NASDAQ), (1) the creation of a conditional share capital in the amount of CHF 580,000 destined for employee participation (capital-actions conditionnel pour la participation des employés) (the Conditional Share Capital), (2) a one-for-one conversion of all existing preferred shares into ordinary shares, and (3) a revision and restatement of the Articles of Association (as defined below);

(viii) an electronic copy of the articles of association (statuts) of the Company, the form of which was filed as Exhibit 3.1 to the Company's registration statement on Form F-1, filed with the SEC on July 2, 2021 (the Articles of Association); and

(ix) an electronic copy of a certified preliminary excerpt from the Commercial Register of the Canton of Vaud, Switzerland, dated July 13, 2021, relating to the Company (the Excerpt).

No documents, other than the Documents, have been reviewed by us in connection with this opinion. 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.

(r) all authorizations, approvals, consents, licenses, exemptions, other than as required by mandatory Swiss law applicable to the Company or the Articles of Association, and other requirements for the filing of the Registration Statement or for any other activities carried on in view of, or in connection with, the performance of the obligations expressed to be undertaken by the Company in the Registration Statement have been duly obtained or fulfilled in due time and are and will remain in full force and effect, and any related conditions to which the parties thereto are subject have been satisfied.

III. Opinion

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

1. The Company is a corporation (société anonyme) duly incorporated and validly existing under the laws of Switzerland with all requisite corporate power and authority to enter into, to perform and to conduct its business as described in the Articles of Association.

2. The Ordinary Shares that may be issued from the Conditional Share Capital, if and when such Ordinary Shares are issued pursuant to the Articles of Association, the ISOPs, any applicable contractual arrangements and Swiss law, and after the subscription amount for such Ordinary Shares has been paid-in in cash or by way of set-off, and when such Shares have been entered into the Company's book of uncertificated securities, will be validly issued, fully paid as to their nominal value and non-assessable.

IV. Qualifications

The above opinions are subject to the following qualifications:

(a) 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.

(b) The exercise of voting rights and rights related thereto with respect to any Ordinary Shares is only permissible if and when such Ordinary Shares have been validly issued and in any case 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.

(c) We have not investigated or verified the truth or accuracy of the information contained in the Registration Statement, nor have we been responsible for ensuring that no material information has been omitted from it.

(d) Notwithstanding or irrespective of registration of the capital increase with the Commercial Register of the Canton of Vaud, the underlying shareholders' resolutions may be challenged by a dissenting shareholder of the Company or others in court or otherwise. However, we believe that a challenge of the underlying shareholders' resolution by a dissenting shareholder of the Company after registration of the Ordinary Shares with the Commercial Register of the Canton of Vaud, even if successful, would not in itself void such Ordinary Shares.

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

We have issued this opinion as of the date hereof and we assume no obligation to advise you of any changes in fact or in law that are made or brought to our attention hereafter.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and further consent to the reference to our name under the caption "Legal Matters" in the Prospectus. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act.

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

Sincerely yours

Homburger AG
