Investing.com - Goldman Sachs initiated coverage on Omnicom Group (NYSE:OMC) with a buy rating and a price target of $146.00 on Wednesday.
The investment bank set the price target based on a discounted cash flow analysis. Omnicom completed its merger with Interpublic Group on November 26, 2025, creating the largest global marketing and communications holding company with combined pro-forma 2025 revenue of approximately $26.5 billion.
Goldman Sachs cited three drivers for its positive view: sustained organic growth of mid-single digits from 2026 to 2030, limited client losses following the merger, and significant margin expansion from synergy realization. The firm expects adjusted EBITA margins to expand to more than 20% by 2027 from 15.3% pro-forma in 2025.
The combined company holds leading positions across integrated media, advertising, public relations, health, and experiential disciplines. Goldman Sachs forecasts approximately $4 billion in share buybacks in 2026 following a $5 billion authorization by the board in February 2026.
The stock trades at 6 times 2027 estimated price-to-earnings ratio and an 18% free cash flow yield, according to Goldman Sachs. The company currently trades at $75.22, which InvestingPro analysis suggests is undervalued based on its Fair Value assessment. Supporting the buyback narrative, an InvestingPro Tip notes that management has been aggressively repurchasing shares, while the company has maintained dividend payments for 56 consecutive years with a current yield of 4.25%.
