• international, national or local economic conditions that could adversely affect Omnicom, IPG or their respective clients;

• losses on media purchases and production costs incurred on behalf of clients;

• reductions in client spending, a slowdown in client payments or a deterioration or disruption in the credit markets;

• unanticipated changes related to competitive factors in the marketing and communications services industries;

• unanticipated changes to, or the ability to hire and retain key personnel;

• currency exchange rate fluctuations;

------

• reliance on information technology systems and risks related to cybersecurity incidents;

• effective management of the risks, challenges and efficiencies presented by utilizing artificial intelligence (AI) technologies and related partnerships;

• changes in legislation or governmental regulations affecting Omnicom, IPG or their respective clients;

• risks associated with assumptions made in connection with acquisitions, critical accounting estimates and legal proceedings;

• risks related to international operations, which are subject to the risks of currency repatriation restrictions, social or political conditions and an evolving regulatory environment in high-growth markets and developing countries;

• risks related to environmental, social and governance goals and initiatives, including impacts from regulators and other stakeholders, and the impact of factors outside of Omnicom's and IPG's respective control on such goals and initiatives;

• the outcome of the Exchange Offers and Consent Solicitations; and

• other business, financial, operational and legal risks and uncertainties detailed from time to time in Omnicom's and IPG's SEC filings.

The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that may affect Omnicom's and IPG's businesses, including those described in Omnicom's and IPG's respective Annual Reports on Form 10-K and in other documents filed from time to time with the Securities and Exchange Commission.

(1) As of August 11, 2025.

(2) For each $1,000 principal amount of Existing IPG Notes accepted for exchange.

(3) The Consent Payment and the Early Tender Payment will be paid to Eligible Holders (as defined herein) on the
settlement date. In order to be eligible to receive the Consent Payment, Eligible Holders of Existing IPG Notes must, at or prior to the Early Tender Date (as defined herein), validly deliver and not validly revoke their related consents, even if
such person is no longer the beneficial owner of such Existing IPG Notes on the Expiration Date (as defined herein).

(4) The New Omnicom Notes will accrue interest from (and including) the most recent date on which interest has been
paid on the corresponding series of Existing IPG Notes accepted in the Exchange Offers. If, at the Early Tender Date, Majority Noteholder Consents have been received, then the Exchange Consideration for each $1,000 principal amount of Existing IPG
Notes tendered after the Early Tender Date and not validly withdrawn at or prior to the Expiration Date will equal $1,000 principal amount of the applicable series of the New Omnicom Notes.

(5) Includes the Consent Payment and the Early Tender Payment.

Eligible Holders who (i) validly tender and do not validly withdraw their Existing IPG Notes at or prior to 5:00 p.m., New York City time, on August 22, 2025, unless extended (the "Early Tender Date") or terminated, (ii) validly deliver and do not validly revoke their related consent in the applicable Consent Solicitation at or prior to the Early Tender Date, and (iii) beneficially own such Existing IPG Notes at the Expiration Date, will be eligible to receive the applicable Total Exchange Consideration as set forth in the table above, which includes the applicable Early Tender Payment and Consent Payment as set forth in the table, for all such Existing IPG Notes that are accepted.

Eligible Holders who (i) validly tender and do not validly withdraw their Existing IPG Notes after the Early Tender Date and prior to 5:00 p.m., New York City time, on September 9, 2025, unless extended (the "Expiration Date"), (ii) validly deliver and do not validly revoke their related consents in the applicable Consent Solicitation after the Early Tender Date and prior to the Expiration Date, and (iii) beneficially own such Existing IPG Notes at the Expiration Date, will be eligible to receive (A) $970 principal amount of the applicable series of New Omnicom Notes if consents sufficient to effect the Proposed Amendments are not received by the Early Tender Date or (B) if, at the Early Tender Date, consents sufficient to effect the Proposed Amendments have been received, $1,000 principal amount of such series of New Omnicom Notes ((A) and (B), as applicable, the "Exchange Consideration").

------

The settlement date will be promptly after the Expiration Date and is expected to be within two business days after the Expiration Date. To the extent the completion of the Merger is not anticipated to occur on or before the then-anticipated settlement date, for any reason, Omnicom anticipates extending the Expiration Date until such time that the Merger has been consummated. Any such extension of the Expiration Date will cause a corresponding extension of the settlement date. During any extension of the Expiration Date, all Existing IPG Notes previously tendered (and not validly withdrawn) in an extended Exchange Offer will remain subject to such Exchange Offer and may be accepted for exchange by Omnicom.

Each New Omnicom Note issued in the Exchange Offers for a validly tendered Existing IPG Note will have an interest rate and maturity date that is identical to the interest rate and maturity date of the tendered Existing IPG Note, as well as identical interest payment dates and optional redemption prices. The New Omnicom Notes will be general unsecured senior obligations of Omnicom and will rank equally in right of payment with all of Omnicom's other unsecured senior indebtedness. The terms of the covenants, related exceptions to such covenants and the events of default, among other provisions, to which the New Omnicom Notes are subject are materially different than the covenants, related exceptions and events of default to which the Existing IPG Notes are subject. Eligible Holders should refer to the Statement for more information on the terms of the New Omnicom Notes.

The New Omnicom Notes will only be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. No tender of Existing IPG Notes will be accepted if it results in the issuance of less than the minimum authorized denomination principal amount of New Omnicom Notes. If, pursuant to the Exchange Offers, a tendering Eligible Holder would otherwise be entitled to receive a principal amount of New Omnicom Notes that is not equal to the minimum authorized denomination or an integral multiple of $1,000 in excess thereof, such principal amount will be rounded down to the minimum authorized denomination or the nearest integral multiple of $1,000 in excess thereof, and such Eligible Holder will receive pursuant to the Exchange Offers this rounded principal amount of New Omnicom Notes plus (a) cash equal to the principal amount of New Omnicom Notes not received as a result of rounding down, and (b) cash equal to the accrued and unpaid interest on the Existing IPG Notes that are validly tendered and not validly withdrawn, but are not exchanged for New Omnicom Notes as a result of rounding down.

Each Exchange Offer and Consent Solicitation is subject to the satisfaction of certain conditions, including among other things, the completion of the Merger and the completion of each of the other Exchange Offers and receipt of the Majority Noteholder Consents in each of the Consent Solicitations. Eligible Holders of Existing IPG Notes will not receive the Exchange Consideration or the Total Exchange Consideration, as applicable, unless such conditions are met or are otherwise waived by Omnicom (other than the condition that the Merger shall have been completed). The parties' obligations to complete the Merger are conditioned upon (i) the receipt of remaining regulatory approvals and (ii) certain other customary closing conditions. The completion of the Merger is not subject to the completion of the Exchange Offers or Consent Solicitations.

------

Eligible Holders may not deliver a consent in the Consent Solicitations without tendering Existing IPG Notes in the applicable Exchange Offer. If an Eligible Holder tenders Existing IPG Notes in an Exchange Offer, such Eligible Holder will be deemed to deliver its consent with respect to the principal amount of such tendered Existing IPG Notes to the corresponding Proposed Amendments. Tenders of Existing IPG Notes may be withdrawn at any time prior to the Expiration Date; however the related consent delivered by such Eligible Holder may not be withdrawn after the earlier of (i) 5:00 p.m., New York City time, on the Early Tender Date and (ii) the date the applicable supplemental indenture to the Existing IPG Indenture implementing the Proposed Amendments to the Existing IPG Notes Indenture is executed (the earlier of (i) and (ii), the "Consent Revocation Deadline"). An Eligible Holder that validly tenders Existing IPG Notes and validly delivers (and does not validly revoke) a consent prior to the Early Tender Date, but withdraws such Existing IPG Notes after the Early Tender Date but prior to the Expiration Date, will receive the Consent Payment, even if such Eligible Holder is no longer the beneficial owner of such Existing IPG Notes at the Expiration Date. Omnicom may complete the Exchange Offers even if valid consents sufficient to effect the Proposed Amendments to the applicable Existing IPG Indenture are not received.

The Statement and other documents relating to the Exchange Offers and Consent Solicitations will only be distributed to holders of Existing IPG Notes who complete and return a letter of eligibility certifying that they are (i) "qualified institutional buyers" within the meaning of Rule 144A under the Securities Act of 1933, as amended ("Securities Act") or (ii) not "U.S. persons" and are outside of the United States within the meaning of Regulation S under the Securities Act and who are "non-U.S. qualified offerees" (as defined in the Statement) (such persons, "Eligible Holders"). Only Eligible Holders are authorized to receive and review the Statement and only Eligible Holders are permitted to tender Existing IPG Notes in the Exchange Offers and deliver consents in the Consent Solicitations. Eligible Holders of Existing IPG Notes who desire to obtain and complete the letter of eligibility and obtain copies of the Statement should call D.F. King & Co., Inc., the Exchange and Information Agent, at (800) 290-6432 (toll-free) or (212) 401-9970 (collect for banks and brokers). Information related to the Exchange Offers and Consent Solicitations, together with any updates, will be available at www.dfking.com/omnicom.

Among other risks described in the Statement, the Exchange Offers and Consent Solicitations are expected to result in reduced liquidity for the Existing IPG Notes that are not exchanged and, if adopted, the Proposed Amendments to the Existing IPG Indenture will reduce protection to remaining holders of Existing IPG Notes. Eligible Holders should refer to the Statement for more details on the risks related to the Exchange Offers and Consent Solicitations.

Omnicom has engaged BofA Securities, Inc., J.P. Morgan Securities LLC and Wells Fargo Securities, LLC as Dealer Managers and Solicitation Agents for the Exchange Offers and Consent Solicitations. Please direct questions regarding the Exchange Offers and Consent Solicitations to BofA Securities, Inc. at (888) 292-0070 (toll-free) or (980) 387-3907 (collect for banks and brokers), J.P.

------

The New Omnicom Notes will not be registered under the Securities Act or any state or foreign securities laws, and they may not be offered or sold absent registration except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and any applicable state and foreign securities laws. The Statement has not been filed with or reviewed by the federal or any state securities commission or regulatory authority of any country, nor has any such commission or authority passed upon the accuracy or adequacy of the Statement. Any representation to the contrary is unlawful and may be a criminal offense.

None of Omnicom, IPG, any of their respective directors or officers, the Dealer Managers or the Exchange and Information Agent, or in each case, any of their respective affiliates, makes any recommendation as to whether or not Eligible Holders should tender or refrain from tendering all or any portion of the Existing IPG Notes in response to the Exchange Offers, or deliver consents in response to the Consent Solicitations. Eligible Holders will need to make their own decision as to whether to tender Existing Notes in the Exchange Offer and participate in the Consent Solicitations and, if so, the principal amount of Existing IPG Notes to tender.
