Presentation of Financial Statements

Presentation of Financial Statements

The terms “Omnicom,” “the Company,” “we,” “our” and “us” each refer to Omnicom Group Inc. and its subsidiaries, unless the context indicates otherwise. The accompanying unaudited consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP or GAAP, for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures have been condensed or omitted. All intercompany balances and transactions have been eliminated. The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could differ from those estimates and assumptions. Unless otherwise noted, dollars in tables are in millions, except per share amounts.

In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation, in all material respects, of the information contained herein. These unaudited consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024, or 2024 10-K. Results for the interim periods are not necessarily indicative of results that may be expected for the year.

Agreement to Acquire IPG

On December 8, 2024, Omnicom entered into an Agreement and Plan of Merger, or the Merger Agreement, by and among Omnicom, EXT Subsidiary Inc., a direct wholly owned subsidiary of Omnicom, or Merger Sub, and The Interpublic Group of Companies, Inc., or IPG, pursuant to which, subject to the terms and conditions of the Merger Agreement, Merger Sub will merge with and into IPG, or the Merger, with IPG surviving the Merger as a wholly owned subsidiary of Omnicom. On March 18, 2025, the shareholders of each of Omnicom and IPG approved the Merger. The completion of the Merger is subject to customary closing conditions, including required regulatory approvals, which are ongoing. If completed, the Merger is expected to have a material impact on our ongoing results of operations and financial condition. In the first quarter of 2025, we recorded $33.8 million of acquisition related costs related to the Merger in selling, general and administrative expenses. The results of IPG are not included in our 2025 or 2024 results of operations or financial position.

Risks and Uncertainties

Global economic conditions and disruptions, including geopolitical events, international hostilities, acts of terrorism, public health crises, inflation or stagflation, tariffs and other trade barriers, central bank interest rate policies in countries that comprise our major markets, labor and supply chain issues affecting the distribution of our clients’ products, or a disruption in the credit markets could cause economic uncertainty and volatility. The impact of these issues on our business will vary by geographic market and discipline. We monitor economic conditions closely, as well as client revenue levels and other factors. In response to reductions in revenue, we can take actions to align our cost structure with changes in client demand and manage our working capital. However, there can be no assurance as to the effectiveness of our efforts to mitigate any impact of the current and future adverse economic conditions, reductions in client revenue, changes in client creditworthiness and other developments.

Accounting Changes

On January 1, 2025, ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), became effective and requires, among other things, greater disaggregation of information in the rate reconciliation and for paid income taxes to be disaggregated by jurisdiction. ASU 2023-09 affects financial statement disclosure only, which is not required until year end 2025 and, as a result, does not affect our results of operations or financial condition.
