Re: €600,000,000 Aggregate Principal Amount of 3.700% Senior Notes Due 2032 of Omnicom Finance Holdings plc

Ladies and Gentlemen:

We have acted as English counsel to Omnicom Finance Holdings plc, a public limited company organised under the laws of England and Wales with registered number 11432221 (the “Issuer”) in connection with the issuance and sale of €600,000,000 aggregate principal amount of 3.700% Senior Notes due 2032 of the Issuer (the “Notes”) pursuant to an indenture, dated as of 6 March 2024 (the “Base Indenture”), by and among the Issuer, Omnicom Group Inc., a New York corporation as guarantor (the “Guarantor”) and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as supplemented by a first supplemental indenture, dated as of 6 March 2024 (the “Supplemental Indenture”), by and among the Issuer, the Guarantor and the Trustee (the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”).

1. SCOPE OF REVIEW AND RELIANCE

For the purposes of giving this opinion (the “Opinion”), we have only examined the following documents (items (a) through (d), inclusive, are referred to herein, collectively, as the “Opinion Documents”):

(a) a signed scanned copy of the Indenture;

(b) copies of the certificate of incorporation, memorandum and articles of association of the Issuer, in each case obtained from the Company Search referred to below;

(c) certified copies of the minutes of a meeting of the board of directors of the Issuer held on 22 February 2024 at which the directors of the Issuer, amongst other things, passed resolutions relating to the Opinion Documents and a meeting of the board of directors of the Issuer held on 28 February 2024 at which the directors of the Issuer, amongst other things, passed resolutions approving the final terms on which the Issuer will issue the Notes. Both sets of minutes are collectively the “Minutes” and both sets of resolutions are collectively the “Resolutions”; and

We have only made and relied upon the following searches and enquiries for the purpose of giving this Opinion:

(a) an online search on 2 February 2024 and updated on 6 March 2024 of the public documents of the Issuer kept at Companies House in Cardiff (the “Company Search”); and

The Registration Statement, the Indenture and the Notes are hereinafter collectively referred to as the “Transaction Documents”.

(d) each of the parties to the Transaction Documents, other than the Issuer, is able lawfully to enter into such Transaction Documents;

(e) each corporate party (other than the Issuer) is duly organised, validly existing and in good standing (where such concept is legally relevant) under the laws of its jurisdiction of incorporation and has the capacity, power and authority to execute and deliver the Transaction Documents to which it is a party, and to exercise its rights and perform its obligations under the Transaction Documents to which it is a party;

Continued 4

(k) the absence of mutual mistake of fact, of any facts or matters which were not revealed by the Transaction Documents or of any other arrangements, documents, agreements or course of dealing between any of the parties to the Transaction Documents which modify or supersede any of their terms or that would result in the inclusion of any additional terms in any of them or would affect this Opinion;

(n) none of the parties to the Transaction Documents is or will be seeking to achieve any purpose not apparent from the Transaction Documents which might render any of them illegal, void or unenforceable;

(o) the truth, accuracy, correctness and completeness in all respects of all information, statements, certifications, acknowledgements, confirmations and representations and warranties (with the exception of representations and warranties on matters on which we have specifically and expressly given our opinion in this Opinion) contained in the Opinion Documents and that all the terms and conditions of the Transaction Documents will be observed and performed by all the parties thereto;

(p) the Issuer is neither an authorised person nor an exempt person in relation to the regulated activity of accepting deposits under the FSMA;

3. LIMITATIONS

This Opinion is given only with respect to English law and HM Revenue and Customs’ practice in force and published at the date of this Opinion as applied by the English courts as at the date of this Opinion. By giving this Opinion, we do not assume any obligation to notify you of future changes in English law or HM Revenue and Customs’ practice or their application which may affect the opinions expressed in this Opinion, or otherwise to update this Opinion in any respect. We have made no investigation of, and therefore express or imply no opinion as to, the laws of any other jurisdiction or as to the application of English or any other law by any other courts. In particular we express no opinion on European Union law (as assimilated within English law, following the United Kingdom’s departure from the European Union) as it affects any jurisdiction other than England. To the extent that the laws of any jurisdiction other than England may be relevant, we have made no independent investigation thereof and this Opinion is subject to the effect of such laws, including as to matters of New York law.

The Indenture and the Notes will be governed by the laws of the State of New York. We have made no investigation of such laws and do not express or imply any opinion on such laws. In addition, we have assumed that, so far as the laws of the State of New York and US securities laws are concerned, the Indenture and the Notes will, on issue in accordance with the Indenture, constitute legal, valid and binding obligations of the Issuer and that such laws do not qualify or affect our opinion as set out below.

4. OPINIONS

4.1 The Issuer has been incorporated and registered as a public limited company in England and Wales under the Companies Act 2006.

Continued 7

4.2 The Issuer has corporate power to enter into and perform its obligations under the Indenture and to issue and perform its obligations under the Notes.

4.3 The issue of the Notes has been duly authorised by all necessary corporate action by the Issuer and when (a) the Registration Statement has become effective under the Securities Act and (b) the Notes have been duly executed by the Issuer and authenticated in accordance with the terms of the Indenture and delivered in the manner provided in the Indenture, we would expect the English courts to recognise the choice of law of New York law as the governing law of the Notes and to enforce by way of a separate action a final and conclusive judgment (which does not re-open an earlier judgment from the same jurisdiction) for a definite sum of money or for a sum of money ascertainable by arithmetical calculation (in either case not being a sum payable in respect of taxes or other charges of a like nature or in respect of a fine or other penalty), entered against the Issuer in connection with the enforcement of the contractual obligations in the Notes, given in civil proceedings in a court of competent jurisdiction in the State of New York.

5. QUALIFICATIONS

Nothing in this opinion shall be taken as implying that an English court would exercise jurisdiction in any proceedings relating to the Indenture or the Notes or accordingly that any remedy would be available in England for the enforcement of obligations arising under the Indenture or the Notes.

This opinion is subject to the following:

(a) The opinions in this Opinion are strictly limited to the matters stated in paragraph 4 and do not extend to any other matters. We express no opinion as to matters of fact or regulatory capital matters. We have not been responsible for investigating or verifying the accuracy of the facts (including statements of foreign law), or the reasonableness of any statement of opinion or intention, contained in or relevant to any document referred to in this Opinion, or that no material facts have been omitted therefrom.

(b) The Company Search is not capable of revealing conclusively whether or not (i) a winding-up order has been made or a resolution passed for the winding-up of a company, (ii) an administration order has been made, or (iii) a receiver, administrative receiver, administrator, moratorium monitor or liquidator has been appointed, since notice of these matters may not be filed with the Registrar of Companies immediately and, when filed, may not be entered on the public database or recorded on the public microfiches of the relevant company immediately. In addition, the Company Search is not capable of revealing whether or not a winding-up petition has been presented or an application for an administration order has been made nor will the search conclusively reveal whether a charge or other restriction or prohibition has been created in relation to the real property owned by the relevant party. We have not verified that the certified copies of the memorandum and articles of association supplied to us are identical to the memorandum and articles of association disclosed by the Company Search.

(c) The Enquiry relates only to a compulsory winding-up and is not capable of revealing conclusively whether or not a winding-up petition in respect of a compulsory winding-up has been presented, since details of the petition may not have been entered on the records of the Central Registry of Winding-up Petitions immediately or, in the case of a petition presented to a County Court, may not have been notified to the Central Registry and entered on such records at all, and the response to an enquiry only relates to current petitions (and not those which may have been subsequently withdrawn or otherwise dealt with)

Continued 8

(d) Laws relating to liquidation or administration or other laws or procedures affecting generally the enforcement of creditors’ rights may affect any obligations of the Issuer under the Transaction Documents and the remedies available.

(e) Under the rules of procedure, an English court may, in certain circumstances, order a claimant in an action to provide security for costs.

(f) Any provision in any Transaction Document that has the effect of imposing an obligation based on or resulting from any law or regulation that is the subject of Council Regulation (EC) No 2271/1996 of 22 November 1996 protecting against the effects of the extra-territorial application of legislation adopted by a third country, and actions based thereon or resulting therefrom (as amended) as it forms part of assimilated EU law under the European Union (Withdrawal) Act 2018 or any other anti-boycott law may be unlawful and unenforceable.

(g) This Opinion is subject to the direct or indirect effects of the National Security and Investment Act 2021 and any regulations made under it (together, the “NSI Act”) in relation to any party to any Transaction Document or any transaction contemplated by any Transaction Document. Any review of, or due diligence on, the direct or indirect effects of the NSI Act in relation to any party to any Transaction Document or the transactions contemplated by any Transaction Document is beyond the scope of this Opinion. We express no Opinion on the application or potential application of the NSI Act in relation to any party to any Transaction Document or any transaction contemplated by any Transaction Document.

(h) The Registration Statement has been prepared by the Issuer and the Company, who have accepted responsibility for the information contained therein. 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.

(i) An English Court will not apply a chosen foreign law if: (i) it is not pleaded and proved; (ii) to do so would be contrary to the mandatory rules of English law or of such chosen foreign law or manifestly incompatible with English public policy; or (iii) the choice is not valid under the chosen law. In the English courts, foreign law is treated as a matter of fact and must be pleaded by the party relying on that law and, save in limited exceptions, must be proved by evidence. We express no opinion as to whether satisfactory evidence of the laws of any jurisdiction could be pleaded and proved as a fact in any proceedings before the English courts.

(j) There are no reciprocal arrangements in force between the State of New York or the United States of America and the United Kingdom for the recognition or enforcement of judgments. Accordingly, a judgment by the courts of the State of New York, United States of America or, as the case may be, any federal court of the United States of America (each such court being a “US Court”) is not enforceable directly in England but may be recognised by the English courts according to common law principles. A judgment by a US Court will not be enforced by the English courts if:

(i) that US Court had no jurisdiction, as a matter of English law, over the defendant;

(ii) the judgment was given in default of appearance and the defendant was not served with process in sufficient time and in such a way as to enable him to arrange for his defence, unless the defendant failed to commence proceedings to challenge the judgment when it was possible for him to do so;

Continued 9

(iii) the proceedings in which the judgment was given were opposed to natural justice;

(iv) the judgment was obtained by fraud;

(v) the enforcement of the judgment would be contrary to English public policy or the Human Rights Act 1998;

(vi) an order has been made and remains effective under section 9 of the Foreign Judgments (Reciprocal Enforcement) Act 1933 applying that section to judgments of that US Court;

(vii) before the date on which the US Court gave judgment, the matter in dispute had been the subject of a final judgment of another court having jurisdiction between the same parties or their privies, that judgment is enforceable in England, and that judgment conflicts with the judgment intended to be enforced in England;

(viii) the judgment is for multiple damages within the meaning of section 5(3) of the Protection of Trading Interests Act 1980 or based on a claim for contribution in respect of the same;

(ix) the judgment is based on a rule of law specified by the relevant Secretary of State as concerned with the prohibition of restrictive trade practices or based on a claim for contribution in respect of the same;

(x) the judgment is based on foreign measures which the relevant Secretary of State specifies as regulating and controlling international trade and which, in so far as they apply to persons carrying on business in the United Kingdom, are damaging or threaten to damage the trading interests of the United Kingdom; or

(xi) the bringing of proceedings in that US Court was contrary to an agreement under which the dispute in question was to be settled otherwise than by proceedings in that US Court.

If the English court gives judgment for the sum payable under a judgment of the courts of the State of New York, the English judgment would be enforceable by the methods generally available for the enforcement of English judgments. These give the court a discretion whether to allow enforcement by any particular method. In addition, it may not be possible to obtain an English judgment or to enforce any English judgment if the judgment debtor is subject to any insolvency or similar proceedings, if there is delay, if an appeal is pending or anticipated against the English judgment in England or against the foreign judgment in the courts of the State of New York or if the judgment debtor has any set-off or counterclaim against the judgment creditor.

Continued 10

Furthermore, there is doubt as to the enforceability in England and Wales of US judgments in respect of civil judgments predicated purely on US securities law.

(k) English courts can give judgments in currencies other than pounds sterling if, subject to the terms of the contract, another currency is the currency which most fairly expresses the claimant’s loss but judgments of this nature may be required to be converted into pounds sterling for execution purposes.

(l) No account has been taken in this opinion of the future exercise of powers by the UK Government pursuant to section 5(4) of the Protection of Trading Interests Act 1980.

(m) We express no opinion as to compliance or otherwise with the financial limitations on borrowings by the Issuer contained in its articles of association.

(n) We give no opinion as to tax or as to any liability to tax.

(o) We have not considered the particular circumstances of any party to the Transaction Documents nor the effect of any such particular circumstances on the Transaction Documents or the effect of the transaction contemplated by the Transaction Documents on any such particular circumstances.

This Opinion is given on the basis that it and any non-contractual obligations arising out of it are governed by and shall be construed in accordance with English law as at today’s date, and is given to the Issuer in connection with the registration under the Securities Act of the Notes. The English courts shall have exclusive jurisdiction in relation to all disputes arising out of or in connection with this Opinion.

This Opinion is rendered to you and is solely for your benefit in connection with the transactions covered hereby. This Opinion may not be relied upon by you for any other purpose, or furnished to, quoted to or relied upon by any other person, firm or corporation for any purpose, without our prior written consent. Notwithstanding the foregoing, we consent to the filing of this Opinion as an exhibit to the Registration Statement and to the reference to us under the heading “Validity of Securities” in the prospectus that is a part of the Registration Statement. In giving such consent, we do not admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the US Securities and Exchange Commission thereunder.

Yours faithfully,
