This is likely to drive both top-line revenue growth and margin expansion post-closing.

Omnicom Group Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Omnicom Group's revenue will grow by 2.8% annually over the next 3 years.
• Analysts assume that profit margins will increase from 8.7% today to 9.8% in 3 years time.
• Analysts expect earnings to reach $1.7 billion (and earnings per share of $9.58) by about September 2028, up from $1.4 billion today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 13.4x on those 2028 earnings, up from 10.9x today. This future PE is lower than the current PE for the US Media industry at 20.3x.
• Analysts expect the number of shares outstanding to decline by 0.7% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.5%, as per the Simply Wall St company report.

Omnicom Group Future Earnings Per Share Growth

Risks

• The rapid adoption and proliferation of advanced AI content creation tools (e.g., Google's Veo 3, Sora) increases the risk that brands will internalize campaign production or use self-service digital ad platforms, potentially reducing demand for agency services and putting downward pressure on Omnicom's top-line revenue and margins.
  
• Persistent fee compression and industry-wide shifts to project-based work, coupled with client demands for efficiency gains delivered by AI, threaten Omnicom's revenue stability and risk compressing net margins as traditional retainer relationships become less prevalent.
  
• Omnicom's reliance on large-scale client relationships, at a time when major multinational clients are building in-house capabilities and using more flexible engagement models, could drive greater revenue volatility and loss of pricing power, negatively impacting long-term earnings predictability.
  
• Increasing regulatory scrutiny and consumer data privacy laws (e.g., GDPR, CCPA) may curtail the effectiveness and scalability of Omnicom's data-driven platforms and targeted advertising services-particularly as reliance on proprietary data and identity solutions grows-which could limit future revenue growth opportunities.
  
• The pending integration of Interpublic introduces significant execution and cultural risks, including the potential for client attrition, unforeseen integration costs, and delays in capturing anticipated cost synergies, all of which may lead to earnings dilution or missed financial targets over the medium term.

Valuation

• The analysts have a consensus price target of $96.333 for Omnicom Group based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $115.0, and the most bearish reporting a price target of just $78.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $17.3 billion, earnings will come to $1.7 billion, and it would be trading on a PE ratio of 13.4x, assuming you use a discount rate of 7.5%.
• Given the current share price of $77.73, the analyst price target of $96.33 is 19.3% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
