Why Interpublic Group (IPG) is a High-Conviction Momentum Buy in a Shifting Marketing Landscape

In a world where marketing is rapidly evolving from traditional ad campaigns to hyper-personalized digital experiences, Interpublic Group (IPG) stands out as a rare blend of resilience and innovation. Leveraging Zacks Investment Research's proprietary analytics, IPG emerges as a high-conviction momentum stock, defying macroeconomic headwinds in the advertising sector while demonstrating robust earnings revisions and strategic adaptability. For investors seeking exposure to a sector poised for digital transformation, IPG's current valuation and operational momentum make it a compelling case study.

Zacks' Proprietary Analytics: A Framework for Momentum Investing

Zacks' methodology for identifying momentum stocks hinges on three pillars: earnings estimate revisions, price performance, and industry positioning. IPG checks all boxes.

1. Earnings Momentum and Revisions:
   Over the past 60 days, three analysts have raised their fiscal 2025 earnings estimates for IPG, pushing the Zacks Consensus Estimate to $2.88 per share—a $0.25 upward adjustment. This trend reflects growing confidence in IPG's ability to navigate client account churn and macroeconomic volatility. The company's 10.7% average earnings surprise—a metric that measures how consistently actual results exceed forecasts—further underscores its operational discipline.

2. Momentum-Driven Valuation:
   IPG's Zacks Rank #1 (Strong Buy) and Momentum Style Score of B signal strong alignment with trend-following strategies. Despite a 17.8% one-year decline, the stock has surged 5.2% in four weeks and 0.5% in a single week, outpacing broader market declines. This short-term resilience, coupled with a VGM Score of B (which combines value, growth, and momentum metrics), positions IPG as a stock with both near-term catalysts and long-term structural appeal.

3. Industry Resilience Amid Macroeconomic Shifts:
   The Advertising and Marketing industry, where IPG operates, is navigating a post-pandemic landscape marked by digital acceleration and budget reallocations. Zacks notes that the industry's forward P/E ratio of 9X is significantly lower than the S&P 500's 22.85X, suggesting undervaluation. IPG's focus on media trading, commerce, and AI-driven marketing aligns with these trends, enabling it to capture growth in high-margin digital services.

Strategic Tailwinds: AI, Mergers, and Global Expansion

IPG's momentum is not purely algorithmic—it's driven by tangible strategic moves. The company is embedding artificial intelligence into its workflows, enhancing client outcomes through data-driven insights. Additionally, its pending merger with Omnicom (expected in late 2025) is a game-changer. By combining complementary capabilities and global talent pools, the merger is projected to boost adjusted EBITA margins and reduce organic net revenue declines.

Macroeconomic indicators also favor IPG. The U.S. GDP grew 3% in Q2 2025, reversing a Q1 contraction, while the Services PMI has remained above 50 for 12 of 13 months, signaling sustained demand for non-manufacturing services like advertising. As businesses prioritize digital transformation and customer-centric strategies, IPG's expertise in these areas becomes increasingly valuable.

Risks and Mitigants

No momentum play is without risks. IPG's organic net revenue declined 3.5% in Q2 2025, driven by client account turnover. However, the company has offset this with cost reductions, restructuring, and margin expansion. Its adjusted EBITA margin of 18.1% in Q2 2025—well above the 16.6% previously forecasted—demonstrates operational flexibility.

Moreover, the advertising sector's cyclical nature means IPG's performance could dip during economic downturns. Yet, its dividend consistency (e.g., $479.1 million distributed in 2024) and international diversification provide a buffer.

Investment Thesis: A Momentum Play with Structural Upside

For investors, IPG represents a rare intersection of short-term momentum and long-term strategic positioning. The Zacks Rank #1 rating, combined with a 5.2% price surge in four weeks and positive earnings revisions, creates a high-conviction case. The company's focus on AI, digital marketing, and global expansion aligns with macroeconomic trends, while the Omnicom merger offers a clear catalyst for margin improvement.

Conclusion: Timing the Momentum

In a shifting marketing landscape, IPG's ability to adapt—through technology, mergers, and operational efficiency—positions it as a standout momentum stock. While the broader sector faces headwinds, Zacks' analytics highlight IPG's resilience, valuation, and earnings trajectory as key differentiators. For investors with a medium-term horizon, IPG offers a compelling opportunity to capitalize on a sector in transition.

Final Call to Action:
Given its Strong Buy Zacks Rank, positive earnings revisions, and strategic tailwinds, IPG deserves a place in momentum-focused portfolios. Investors should monitor the Omnicom merger timeline and Q3 2025 earnings report for further validation of its momentum thesis.
