To Viatris Inc.:

We have acted as legal counsel as to Dutch law to Viatris Inc. and the Company in connection with the filing of the Registration Statement with the SEC. This opinion letter is rendered to you in order to be filed with the SEC as an exhibit to the Registration Statement.

Capitalised terms used in this opinion letter have the meanings set forth in Exhibit A to this opinion letter. The section headings used in this opinion letter are for convenience of reference only and are not to affect its construction or to be taken into consideration in its interpretation.

This opinion letter is strictly limited to the matters stated in it and may not be read as extending by implication to any matters not specifically referred to in it. Nothing in this opinion letter should be taken as expressing an opinion in respect of any representations or warranties, or other information, contained in any document reviewed by us in connection with this opinion letter, except as expressly confirmed in this opinion letter.

In rendering the opinions expressed in this opinion letter, we have reviewed and relied upon the Registration Statement, the Form of Indenture, the Form of Notation of Guarantee and pdf copies of the Corporate Documents and we have assumed that any issuance of Registered Securities or the entering of any Agreements shall be effected for bona fide commercial reasons. We have not investigated or verified any factual matter disclosed to us in the course of our review.

This opinion letter sets out our opinion on certain matters of the laws with general applicability of the Netherlands, and, insofar as they are directly applicable in the Netherlands, of the European Union, as at today’s date and as presently interpreted under published authoritative case law of the Dutch courts, the General Court and the Court of Justice of the European Union. We do not express any opinion on Dutch or European competition law, data protection law, tax law, securitisation law or regulatory law. No undertaking is assumed on our part to revise, update or amend this opinion letter in connection with, or to notify or inform you of, any developments and/or changes of Dutch law subsequent to today’s date. We do not purport to opine on the consequences of amendments to the Registration Statement or the Corporate Documents subsequent to the date of this opinion letter.

The competent courts at Amsterdam, the Netherlands, have exclusive jurisdiction to settle any issues of interpretation or liability arising out of or in connection with this opinion letter. Any legal relationship arising out of or in connection with this opinion letter (whether contractual or non-contractual), including the above submission to jurisdiction, is governed by Dutch law and shall be subject to the general terms and conditions of NautaDutilh. Any liability arising out of or in connection with this opinion letter shall be limited to the amount which is paid out under NautaDutilh’s insurance policy in the matter concerned.

The Dutch legal concepts concerned may not be identical in meaning to the concepts described by the English terms as they exist under the law of other jurisdictions. In the event of a conflict or inconsistency, the relevant expression shall be deemed to refer only to the Dutch legal concepts described by the English terms.

For the purposes of this opinion letter, we have assumed that:

a.   drafts of documents reviewed by us will be signed in the form of those drafts, each copy of a document conforms to the original, each original is authentic, and each signature is the genuine signature of the individual purported to have placed that signature;

b.  if any signature under any document is an electronic signature (as opposed to a handwritten (“wet ink”) signature) only, it is either a qualified electronic signature within the meaning of the eIDAS Regulation, or the method used for signing is otherwise sufficiently reliable;

c.   the Registration Statement, in the form reviewed by us, has become or will become effective automatically upon filing with the SEC by Viatris Inc.;

d.  the Current Articles are the Articles of Association currently in force (as supported by the Extract) and as they will be in force at each Relevant Moment;

e.   the Company has not (i) been dissolved (ontbonden), (ii) ceased to exist pursuant to a merger (fusie) or a division (splitsing), (iii) been converted (omgezet) into another legal form, either national or foreign, (iv) had its assets placed under administration (onder bewind gesteld), (v) been declared bankrupt (failliet verklaard), (vi) been granted a suspension of

3

payments (surseance van betaling verleend), (vii) started or become subject to statutory proceedings for the restructuring of its debts (akkoordprocedure) or (viii) been made subject to similar proceedings in any jurisdiction or otherwise been limited in its power to dispose of its assets;

f.   each Power of Attorney (i) is in full force and effect and (ii) under any applicable law validly authorises the person or persons purported to be granted power of attorney thereunder to represent and bind the Company vis-à-vis other parties in relation to the performance of the Company’s obligations under the Agreements and under the Registered Securities, as relevant;

g.  under any applicable law, the Agreements shall constitute the legal, valid and binding obligations of the parties expressed to be a party thereto, enforceable against them in accordance with their terms; and

h.  at each Relevant Moment, each of the assumptions made in this opinion letter will be correct in all aspects by reference to the facts and circumstances then existing.

Based upon and subject to the foregoing and subject to the qualifications set forth in this opinion letter and to any matters, documents or events not disclosed to us, we express the following opinions:

Corporate Status

1.  The Company has been duly incorporated as a besloten vennootschap met beperkte aansprakelijkheid and is validly existing as a besloten vennootschap met beperkte aansprakelijkheid.

Execution of Agreements

2.  Any Agreement when duly signed by all members of the Board, any member of the Board or a holder of a Power of Attorney for such purpose, shall have been duly and validly executed on behalf of the Company.

3.  The Registration Statement has been validly signed on behalf of the Company.

Corporate Power

4.  The Company has the corporate power to enter into any Agreements and to perform its obligations thereunder and to sign the Registration Statement.

4

Corporate Action

5.  The Company has taken all corporate action required by its Articles of Association and Dutch law in connection with the entering into any Agreements and the performance of its obligations thereunder and with the signing of the Registration Statement.

The opinions expressed above are subject to the following qualifications:

A. Opinion 1 must not be read to imply that the Company cannot be dissolved (ontbonden). A company such as the Company may be dissolved, inter alia by the competent court at the request of the company’s board of directors, any interested party (belanghebbende) or the public prosecution office in certain circumstances, such as when there are certain defects in the incorporation of the company. Any such dissolution will not have retro-active effect.

B. The information contained in the Extract does not constitute conclusive evidence of the facts reflected in it.

C. Pursuant to Section 2:7 DCC, any transaction entered into by a legal entity may be nullified by the legal entity itself or its liquidator in bankruptcy proceedings (curator) if the objects of that entity were transgressed by the transaction and the other party to the transaction knew or should have known this without independent investigation (wist of zonder eigen onderzoek moest weten). The Dutch Supreme Court (Hoge Raad der Nederlanden) has ruled that in determining whether the objects of a legal entity are transgressed, not only the description of the objects in that legal entity’s articles of association (statuten) is decisive, but all (relevant) circumstances must be taken into account, in particular whether the interests of the legal entity were served by the transaction. Based on the objects clause contained in the Current Articles, we have no reason to believe that, by entering into any Agreements or by the performance of its obligations thereunder, the Company would transgress the description of the objects contained in its Articles of Association. However, we cannot assess whether there are other relevant circumstances that must be taken into account, in particular whether the interests of the Company are served by entering into any Agreements since this is a matter of fact.

5

D. A power of attorney or mandate granted by the Company will terminate in the event of a bankruptcy and become ineffective upon the suspension of payments of the principal or, unless otherwise provided, the attorney.

E.  The opinions expressed in this opinion letter may be limited or affected by:

a.   rules relating to Insolvency Proceedings or similar proceedings under a foreign law and other rules affecting creditors’ rights generally;

b.  the provisions of fraudulent preference and fraudulent conveyance (Actio Pauliana) and similar rights available in other jurisdictions to insolvency practitioners and insolvency office holders in bankruptcy proceedings or creditors;

c.   claims based on tort (onrechtmatige daad);

d.  sanctions and measures, including but not limited to those concerning export control, pursuant to European Union regulations, under the Sanctions Act 1977 (Sanctiewet 1977) or other legislation;

e.   the Anti-Boycott Regulation, Anti Money Laundering Laws and related legislation;

f.   any intervention, recovery or resolution measure by any regulatory or other authority or governmental body in relation to financial enterprises or their affiliated entities; and

g.  the rules of force majeure (niet toerekenbare tekortkoming), reasonableness and fairness (redelijkheid en billijkheid), suspension (opschorting), dissolution (ontbinding), unforeseen circumstances (onvoorziene omstandigheden) and vitiated consent (i.e., duress (bedreiging), fraud (bedrog), abuse of circumstances (misbruik van omstandigheden) and error (dwaling)) or a difference of intention (wil) and declaration (verklaring).

F.  This opinion letter does not purport to express any opinion or view on the operational rules and procedures of any clearing or settlement system or agency.

We consent to the filing of this opinion letter as an exhibit to the Registration Statement and also consent to the reference to NautaDutilh in the Registration Statement under the caption “Legal
