Interpublic Group of Companies (IPG) sells primarily to other companies, providing a comprehensive range of advertising, marketing, and communication services.

Due to the highly diversified nature of its business and its extensive portfolio of agencies (such as McCann, FCB, MullenLowe, UM, Initiative, and Weber Shandwick), no single client represents a major portion of Interpublic's net revenue. According to their annual filings (e.g., 2022 10-K), no single client accounted for more than 1.5% of their net revenue in 2022.

Instead, IPG serves a vast array of clients across numerous industries globally. While specific client relationships can evolve, examples of major companies and brands that have historically worked with or are currently clients of agencies within the IPG network include:

• General Motors (NYSE: GM)
• Microsoft (NASDAQ: MSFT)
• Unilever (NYSE: UL)
• Johnson & Johnson (NYSE: JNJ)
• American Express (NYSE: AXP)
• Verizon Communications (NYSE: VZ)

These examples illustrate the caliber and breadth of companies that partner with Interpublic's agencies, rather than indicating a concentrated customer base.

• Alphabet Inc. (GOOGL)
• Meta Platforms, Inc. (META)
• Amazon.com, Inc. (AMZN)
• Comcast Corporation (CMCSA)
• The Trade Desk, Inc. (TTD)

The Interpublic Group of Companies (IPG) faces several key business risks, with the impending integration with Omnicom representing the most significant and immediate challenge.

Key Risks to Interpublic Group of Companies (IPG)

1. Omnicom Merger Integration Risks: The acquisition of IPG by Omnicom, which reportedly closed in November 2025, presents substantial integration challenges. These include the risk of client attrition during the transition, the complex task of achieving projected operational synergies, and the potential for cultural differences between the two entities to complicate the integration process. Additionally, retaining key talent and managing potential client conflicts are critical for the combined entity's success. While regulatory hurdles for the merger have largely been cleared, the execution of the integration remains a complex undertaking that could impact client relationships and operational efficiency.
2. Client Account Losses and Revenue Contraction: IPG has been experiencing a notable trend of client account losses and near-term revenue contraction, leading to organic revenue declines in 2025. This pressure on the top line is a persistent concern, with the company forecasting a full-year organic net revenue decrease. The highly competitive and bidding-based nature of the advertising market, coupled with the relatively short duration and low switching costs of agency contracts, exacerbates this risk, as major account losses can significantly impact financial performance.
3. Competitive Environment and Technological Shifts: The advertising and marketing services industry is undergoing rapid transformation driven by new technologies such as Artificial Intelligence (AI) and increasing digital competition. IPG faces a significant threat from both direct competitors and substitutes, including clients opting for in-house marketing teams. To remain competitive, IPG must continuously invest in and adapt to advancements in data and AI capabilities, which is crucial for delivering measurable results and retaining clients in a landscape that increasingly prioritizes data integration.

1. In-housing of Marketing Services

Many large brands are increasingly bringing marketing functions, such as creative development, media planning, and data analytics, in-house. This reduces their reliance on external agencies like IPG, impacting revenue opportunities and shifting the allocation of marketing budgets.

2. Competition from Management and Technology Consultancies

Firms like Accenture Interactive, Deloitte Digital, and IBM iX are aggressively expanding into marketing and advertising services. These consultancies leverage their existing C-suite relationships and expertise in technology and data to offer integrated solutions, directly competing with and often winning large mandates traditionally handled by advertising holding companies.

3. Impact of Data Privacy Regulations and the "Cookie-less Future"

Evolving global data privacy regulations (e.g., GDPR, CCPA) and the deprecation of third-party cookies by major web browsers fundamentally challenge the current models of digital advertising, particularly around targeting, personalization, and measurement. This necessitates significant adaptation and investment for agencies to maintain their value proposition, potentially shifting power towards platforms with proprietary first-party data.
