On August 11, 2025, Omnicom Group Inc. ("Omnicom") and The Interpublic Group of Companies, Inc. ("IPG") issued a joint press release announcing that, in connection with the pending transaction to acquire IPG contemplated by the Agreement and Plan of Merger, dated as of December 8, 2024 (the "Merger"), Omnicom commenced offers to exchange (collectively, the "Exchange Offers") all outstanding senior notes (collectively, the "Existing IPG Notes") issued by IPG for up to (1) $2.95 billion aggregate principal amount of new notes to be issued by Omnicom and (2) cash.

Concurrently with the Exchange Offers, Omnicom is also soliciting consents (collectively, the "Consent Solicitations"), on behalf of IPG, to amend the respective indentures governing the Existing IPG Notes to, among other things, eliminate certain of the covenants, restrictive provisions and events of default and modify or amend certain other provisions.

● 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;

● 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.

(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. Morgan Securities LLC at (866) 834-4666 (toll-free) or (212) 834-3554 (collect for banks and brokers) or Wells Fargo Securities, LLC at (866) 309-6316 (toll free) or (332) 214-6330.

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.

## Exhibit 99.2

**Exhibit 99.2**

**UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS**

On December 8, 2024, Omnicom Group Inc. ("Omnicom") entered into an Agreement and Plan of Merger (the "Merger Agreement"), by and among Omnicom, EXT Subsidiary Inc., a direct wholly owned subsidiary of Omnicom ("Merger Sub"), and The Interpublic Group of Companies, Inc. ("IPG"), pursuant to which, subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into IPG (the "Merger"), with IPG surviving the Merger as a wholly owned subsidiary of Omnicom. Each share of IPG common stock will be converted into, and represent the right to receive, 0.344 shares of common stock of Omnicom, plus cash in lieu of any fractional shares of Omnicom common stock that otherwise would have been issued. On March 18, 2025, the shareholders of each of Omnicom and IPG approved the Merger. On June 23, 2025, Omnicom and IPG announced that the U.S. Federal Trade Commission had concluded its antitrust review of the Merger and reached agreement with Omnicom and IPG on a mutually acceptable consent order. 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 Merger is not subject to a financing condition or the completion of the Exchange Offers or Consent Solicitations announced by Omnicom and IPG on August 11, 2025 related to IPG's outstanding senior notes (the "Exchange Offers and Consent Solicitations"). Omnicom expects the Merger to close in 2025.

The following unaudited pro forma condensed combined financial statements have been prepared in accordance with Article 11 of Regulation S-X and should be read in conjunction with the accompanying notes. The unaudited pro forma condensed combined financial statements have been prepared from the respective historical consolidated financial statements of Omnicom and IPG and reflect transaction accounting adjustments related to the Merger. The unaudited pro forma condensed combined statements of income for the year ended December 31, 2024 and for the six months ended June 30, 2025 are presented as if the Merger had been completed on January 1, 2024. The unaudited pro forma condensed combined balance sheet as of June 30, 2025 is presented as if the Merger had been completed on June 30, 2025.

The unaudited pro forma condensed combined financial statements have been developed from and should be read in conjunction with:

● the unaudited consolidated financial statements of Omnicom included in its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025;

● the unaudited consolidated financial statements of IPG included in its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2025;

● the audited consolidated financial statements of Omnicom included in its Annual Report on Form 10-K for the year ended December 31, 2024;

● the audited consolidated financial statements of IPG included in its Annual Report on Form 10-K for the year ended December 31, 2024; and

● other information relating to Omnicom and IPG contained in reports filed by Omnicom or IPG, as applicable, with the Securities and Exchange Commission under the Securities and Exchange Act of 1934, as amended.

The unaudited pro forma condensed combined financial statements have been prepared to reflect adjustments to Omnicom's historical consolidated financial information representing Omnicom management's estimates based on information available as of August 11, 2025 and are subject to change as additional information becomes available and analyses are performed. However, Omnicom management believes that the assumptions provide a reasonable basis for presenting the significant effects of the Merger as contemplated, and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial statements. Accordingly, the unaudited pro forma condensed combined financial statements reflect the following adjustments, which include transaction accounting adjustments:

● the reclassification of certain items within IPG's historical presentation to conform to Omnicom's financial statement presentation;

● the Merger, using the acquisition method of accounting, with Omnicom as the accounting acquirer and each share of IPG common stock converted into 0.344 shares of Omnicom common stock; and

● estimated purchase accounting adjustments and related impacts on the balance sheet and income statements.

The unaudited pro forma condensed combined financial statements have been prepared using the acquisition method of accounting in accordance with U.S. generally accepted accounting principles. Omnicom has been treated as the acquirer for accounting purposes, primarily due to Omnicom stockholders holding majority voting interests in the combined company, Omnicom issuing equity interests to effect the Merger and the management of Omnicom continuing to manage the combined entity. Thus, Omnicom will account for the Merger as a business combination in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 805, *Business Combinations*. The total purchase price will be allocated to the acquired tangible and intangible assets and assumed liabilities based on their respective fair values. The fair values of the acquired assets and assumed liabilities of IPG have been measured based on various preliminary estimates using assumptions that Omnicom management believes are reasonable and based on currently available information. Accordingly, the pro forma adjustments are preliminary and have been made solely for the purpose of preparing the unaudited pro forma condensed combined financial statements. The final purchase accounting could be materially different from the preliminary estimates used to prepare the accompanying unaudited pro forma condensed combined financial statements which could have a material impact on the combined company's future results of operations and financial position.

The unaudited pro forma condensed combined financial statements have been prepared based on the aforementioned historical financial statements and the assumptions and adjustments as described in the notes to the unaudited pro forma condensed combined financial statements. The pro forma adjustments reflect transaction accounting adjustments related to the Merger, which are discussed in further detail below. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and do not purport to represent the combined company's consolidated results of operations or consolidated financial position that would actually have occurred had the Merger been consummated on the dates assumed or to project the combined company's consolidated results of operations or consolidated financial position for any future date or period.

The accounting policies followed in preparing the unaudited pro forma condensed combined financial statements are those used by Omnicom as set forth in Omnicom's audited historical financial statements. Based on Omnicom's initial review and understanding of IPG's summary of significant accounting policies included in IPG's annual report on Form 10-K for the year ended December 31, 2024, management is not aware of any material differences to conform IPG's historical financial information to Omnicom's significant accounting policies. A more comprehensive comparison and assessment will occur, which may result in additional differences identified. Additionally, Omnicom has included certain reclassifications for consistency in the financial statement presentation, including with respect to certain IPG restructuring charges. These reclassifications have no effect on the previously reported total assets, total liabilities and shareholders' equity, or net income of Omnicom or IPG. See Notes 2 and 3 in the Notes to Unaudited Pro Forma Condensed Combined Financial Statements for more information.

The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only and do not reflect the costs of any post-close integration activities or any cost savings or synergies that may be achieved because of the Merger. The unaudited pro forma condensed combined financial statements do not give effect to the estimated impacts of the Exchange Offers and Consent Solicitations.

IPG and Omnicom have not had any historical material relationship prior to the Merger. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

("Omnicom") entered into an Agreement and Plan of Merger (the "Merger Agreement"), by and among Omnicom, EXT Subsidiary Inc., a direct wholly owned subsidiary of Omnicom ("Merger Sub"), and The Interpublic Group of Companies, Inc. ("IPG"), pursuant to which, subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into IPG (the "Merger"), with IPG surviving the Merger as a wholly owned subsidiary of Omnicom. Each share of IPG common stock will be converted into, and represent the right to receive, 0.344 shares of common stock of Omnicom, plus cash in lieu of any fractional shares of Omnicom common stock that otherwise would have been issued. On March 18, 2025, the shareholders of each of Omnicom and IPG approved the Merger. On June 23, 2025, Omnicom and IPG announced that the U.S. Federal Trade Commission had concluded its antitrust review of the Merger and reached agreement with Omnicom and IPG on a mutually acceptable consent order. 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 closing of the Merger is not subject to a financing condition or the completion of the Exchange Offers or Consent Solicitations announced by Omnicom and IPG on August 11, 2025 related to IPG's outstanding senior notes (the "Exchange Offers and Consent Solicitations").

The unaudited pro forma condensed combined financial statements were prepared in accordance with Article 11 of Regulation S-X. The unaudited pro forma condensed combined financial statements have been prepared from the respective historical consolidated financial statements of Omnicom and IPG and reflect transaction accounting adjustments related to the Merger. The unaudited pro forma condensed combined statements of income for the year ended December 31, 2024 and for the six months ended June 30, 2025 have been presented as if the Merger had been completed on January 1, 2024. The unaudited pro forma condensed combined balance sheet as of June 30, 2025 has been presented as if the Merger had occurred on June 30, 2025.

Certain balance sheet and statements of income reclassifications have been made to the unaudited pro forma condensed combined financial statements in order to align historical presentation between Omnicom and IPG. Refer to Note 2 and Note 3 for a discussion of these reclassification adjustments.

The unaudited pro forma condensed combined financial statements were prepared using the acquisition method of accounting, and Omnicom is considered the accounting acquirer. The acquisition method of accounting, based on ASC 805, uses the fair value concepts defined in ASC 820, Fair Value Measurement ("ASC 820"). Fair value is defined in ASC 820 as the "price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date." This is an exit price concept for the valuation of an asset or liability. Market participants are assumed to be buyers or sellers in the most advantageous market for the asset or liability. Fair value measurement for an asset assumes the highest and best use by these market participants, and as a result, assets may be required to be recorded which are not intended to be used or sold and/or at a fair value measurement that does not reflect management's intended use for those assets. Fair value measurements can be highly subjective, and it is possible the application of reasonable judgment could develop different assumptions resulting in a range of alternative estimates using the same facts and circumstances. ASC 805 requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at fair value as of the Merger date, with any excess purchase price allocated to goodwill.

As of August 11, 2025, the accompanying unaudited estimated purchase price allocation is preliminary and is subject to further adjustments as additional information becomes available and as additional analyses are performed. The potential changes to the purchase price allocation and related pro forma adjustments could be material.

For the purposes of preparing the unaudited pro forma condensed combined financial statements, Omnicom's management has conducted a preliminary analysis of the adjustments required to conform IPG's financial statements to reflect the current accounting policies of Omnicom. This assessment is ongoing, and, at the time of preparing the unaudited pro forma condensed combined financial statements, management is not aware of any material accounting policy differences. Upon consummation of the Merger, Omnicom management will conduct a final review of IPG's accounting policies to determine if differences in accounting policies or financial statement classification exist that may require adjustments to or reclassification of IPG's results of operations, assets or liabilities to conform to Omnicom's accounting policies and classifications. As a result of that review, differences may be identified that, when conformed, could have a material impact on the unaudited pro forma condensed combined financial statements.

**2.** **Summary of Reclassification Adjustments – Balance Sheet** 

The classification of certain balance sheet items presented by IPG under U.S generally accepted accounting principles ("GAAP") has been adjusted to align with the presentation used by Omnicom under GAAP, as shown below.

**4.** **Consideration** 

Omnicom calculated the total consideration as follows (in millions, except for shares, per share amounts and exchange ratio):

---

| | |
|:---|:---|
| Shares of IPG common stock outstanding<sup>1</sup> | 365781784 |
| Exchange ratio | 0.344 |
| Shares of Omnicom common stock to be issued | 125828934 |
| Omnicom share price<sup>2</sup> | $71.11 |
| **Total equity consideration** | $8947.7 |
| Value of unvested replacement awards<sup>3</sup> | $133.6 |
| Total Consideration<sup>4</sup> | $9081.3 |

---

1 Shares of IPG common stock outstanding as of August 1, 2025.

---

| | |
|:---|:---|
| 2 | Omnicom share price is as of the close of business August 1, 2025. The actual value of the shares of Omnicom common stock to be issued in the Merger will depend on the market price of shares of Omnicom common stock at the closing date of the Merger, and therefore the actual consideration will fluctuate based on the market price of the shares of Omnicom common stock. Accordingly, the final consideration could differ significantly from the current estimate. A 10% increase or decrease in Omnicom's share price would increase or decrease the consideration by approximately $894.8 million and impact goodwill by a corresponding amount. |

---

3 Represents the historical share-based awards that will be replaced and cash settled by Omnicom. Refer to (i) in Note 5 below.

4 Consideration paid for fractional shares is immaterial.

Under the acquisition method of accounting, the total consideration is allocated to IPG's assets and liabilities based upon their estimated fair values as of the date of completion of the Merger. Based upon the estimated purchase price and a preliminary valuation, the preliminary purchase price allocation is as follows:

---

| | |
|:---|:---|
| <br>**Preliminary purchase price allocation** | **As of<br> June 30, 2025** |
| Cash and cash equivalents | $1564.4 |
| Accounts receivable | 4850.7 |
| Work in process | 2103.0 |
| Assets held for sale | 1.8 |
| Other current assets | 781.2 |
| Property and Equipment | 339.6 |
| Operating lease right-of-use assets | 891.8 |
| Equity method investments | 44.4 |
| Goodwill | 7374.7 |
| Intangible assets | 4119.4 |
| Other assets | 787.3 |
| **Total assets** | $22858.4 |
| Accounts payable | $7185.9 |
| Customer advances | 654.9 |
| Current portion of debt | 0.1 |
| Short-term debt | 37.6 |
| Other current liabilities | 827.9 |
| Long-term liabilities | 490.6 |
| Long-term liability - operating leases | 977.0 |
| Long-term debt | 2750.3 |
| Deferred tax liabilities | 780.2 |
| Non-controlling interests | 52.6 |
| Redeemable noncontrolling interests | 20.0 |
| **Total liabilities and noncontrolling interests** | $13777.1 |
| **Total Consideration** | $9081.3 |

---

The purchase price estimates and the purchase price allocation are preliminary and are subject to change based on the Omnicom share price at the closing date of the Merger, as well as the actual net tangible and intangible assets and liabilities that exist on the closing date of the Merger, and the value of certain tax contingencies. The purchase price allocation related to certain tangible and intangible assets and liabilities is ongoing. This includes, but is not limited to, items such as property and equipment, operating lease right-of-use assets and lease liabilities, and redeemable noncontrolling interests. The final determination of the purchase price allocation will be completed as soon as practicable after the completion of the Merger and will be based on the fair values of the assets acquired and liabilities assumed. The final amounts allocated to assets acquired and liabilities assumed could differ significantly from the amounts presented in the unaudited pro forma condensed combined financial statements.

Refer to Note 5 for additional information on how the consideration and purchase price allocation have been reflected in the pro forma adjustments.

**5.** **Pro Forma Adjustments** 

The unaudited pro forma condensed combined financial statements reflects the following adjustments.

(a) Acquisition of all outstanding shares of IPG common stock.

---

| | |
|:---|:---|
|  | **As of <br> June 30, 2025** |
| Shares of Omnicom issued to IPG stockholders (Common stock) | $18.9 |
| Shares of Omnicom issued to IPG stockholders (Additional paid-in capital) | 8928.8 |
| Total equity consideration | $8947.7 |

---

(b) Purchase price allocation (the amounts below represent changes; refer to Note 4 for preliminary fair value estimates). The adjustments
as a result of the purchase price allocation include the recognition of new intangible assets, net of the removal of historical intangible
assets, the recognition of new goodwill, net of the removal of historical goodwill, adjustment to the fair value of the debt, and adjustment
to the fair value of deferred taxes to reflect the after tax basis difference of the intangible assets.

---

| | |
|:---|:---|
|  | **As of <br> June 30, 2025** |
| Intangible assets<sup>1</sup> | 3283.7 |
| Goodwill | 2576.6 |
| Debt | (171.8) |
| Deferred income taxes<sup>2</sup> | 569.2 |

---

---

| | |
|:---|:---|
| 1 | The identifiable intangible assets acquired consist of trade names, customer relationships and technology with estimated fair values of $973.0 million , $2,886.0 million and $260.4 million, respectively. Trade names, customer relationships and technology are amortized straight-line over estimated remaining useful lives of 15 years, 10 years and 5 years, respectively. The fair values for intangible assets were estimated using a market participant approach. The fair values for trade names were estimated by applying the relief-from-royalty method under the income approach. The fair values for customer relationships were estimated using the profit contribution method under the income approach. The fair values for the technology intangible assets were estimated based on the historical book value of the similar assets. The final purchase price allocation for intangible assets could materially differ from the estimates. A ten percent increase in the value of the acquired intangible assets would increase the intangible assets by $411.9 million and result in a corresponding increase to amortization expense of $78.5 million. |

---

---

| | |
|:---|:---|
| 2 | Deferred income taxes were adjusted to include deferred tax liabilities related to the identified intangible assets that will be amortized. In addition, estimates were made to deferred taxes related to net operating losses that may not be utilized and withholding taxes on undistributed earnings of foreign subsidiaries that may be required in certain jurisdictions of the combined entities (see (f) below). |

---

(c) Reflects adjustments to equity related to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i) eliminate IPG historical equity of $3,712.4 million; and

ii) give effect to the transaction costs adjustment of $165.0 million described in (d) to retained earnings.

---

| | |
|:---|:---|
|  | **As of <br> June 30, 2025** |
| Common stock | $(37.4) |
| Additional paid-in capital | (460.0) |
| Retained earnings | (4459.3) |
| Accumulated other comprehensive income (loss) | 889.5 |
| Treasury stock, at cost | 189.8 |
| Total | $(3877.4) |

---

(d) Represents the accrual of direct and incremental transaction costs expected to be incurred after June 30, 2025, in connection with
the closing of the Merger, which are non-recurring. The estimate is based on Omnicom management's judgment after evaluating several
factors, including evaluating its most recent overall expected budget for transaction costs and amounts contractually due to external
advisors and service providers. These costs will not affect Omnicom's income statement beyond 12 months after the acquisition date and
costs related to future integration activities are not reflected. The historical income statements of Omnicom include acquisition related
costs of $114.5 million ($14.8 million for the year ended December 31, 2024 and $99.8 million for the six months ended June 30, 2025).

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31, 2024** | **Six Months Ended**<br> **June 30, 2025** |
| Acquisition-related costs | 165.0 |  |

---

(e) Incremental amortization resulting from the preliminary allocation of purchase price.

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31, 2024** | **Six Months Ended**<br> **June 30, 2025** |
| Incremental amortization | 285.9 | 142.4 |

---

(f) Adjust the deferred tax liabilities and deferred tax assets as a result of the Merger. An increase to deferred tax liabilities was
recorded as part of the allocation of purchase price in adjustment (b) above. The income tax effects related to the increase of the acquiree's
net operating loss valuation allowance and the taxes recognized on undistributed earnings of foreign subsidiaries are also presented as
adjustments to purchase accounting.

---

| | |
|:---|:---|
|  | **As of <br> June 30, 2025** |
| Incremental valuation allowance | (29.0) |
| Incremental withholding tax accruals | 65.0 |

---

(g) Adjusts the common shares outstanding to reflect the Omnicom common stock that will be issued as stock consideration and the removal
of IPG's shares.

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31, 2024** | **Six Months Ended**<br> **June 30, 2025** |
| Weighted Average Shares - Basic |  |  |
| Omnicom shares issued | 125.8 | 125.8 |
| IPG shares converted | (375.2) | (370.2) |
| Total | (249.4) | (244.4) |
| Weighted Average Shares - Diluted |  |  |
| Omnicom shares issued | 125.8 | 125.8 |
| IPG shares converted | (377.7) | (372.5) |
| Total | (251.9) | (246.7) |

---

(h) Reflects the adjustments to previously recorded expense for incentive compensation plans that included, performance and restricted
share-based awards and cash performance-based awards granted to certain IPG employees and executives and IPG's Board of Directors.
This reflects the awards that are unvested at the Merger closing date and assumes no grant will be made after the Merger closing date.
The share-based awards of IPG will be replaced with cash-based awards as of the closing date and have been reflected at the estimated
replacement award for share-based awards using the estimated IPG share price at closing. The expense for any awards with a remaining service
period after the closing date has been included in the unaudited pro forma condensed combined financial statements. IPG cash-based and
share-based awards include a change of control provision that requires payment upon both a change of control event and subsequent termination
(double trigger). Adjustments have been made for certain awards that had a double trigger which accelerated the vesting. Where no determination
has been made in relation to the double trigger and whether both criteria requiring payment upon a change in control would be satisfied,
no acceleration has been made.

The adjustment below reflects the impact to selling, general and administrative expenses (SG&A) for those employees whose compensation expense was included within SG&A and Salary and related for those employees included within Salary and related. The following reflects the previously recorded income statement impacts and the adjusted income statement impacts for each period presented.

---

| | | |
|:---|:---|:---|
|  | **Year Ended December 31, 2024** | **Six Months Ended**<br> **June 30, 2025** |
| Previously recognized IPG incentive compensation plan expense | 101.0 | 40.6 |
