Shareholder Activism Is Costly—But It Pays Off

/

New data confirms: shareholder engagement creates long-term value

There’s no denying it—shareholder activism is expensive. Legal fees, data analysis, proxy solicitation, engagement staff—it adds up fast. But a groundbreaking study by Gantchev (2013) used a sequential decision-making model to ask the real question: Is it worth it?

The answer: Yes—especially when targeted at governance reform or capital misallocation.

Gantchev’s study modeled the full lifecycle of activist campaigns, accounting for costs at every stage. He found that successful engagements (those that resulted in changes to capital policy, board structure, or leadership) produced net benefits to shareholders—even after subtracting all expenses.

💡 The Key Takeaway

The most effective campaigns were those that:

  • Chose targets wisely — companies with weak governance and clear value gaps;

  • Had staying power — persistence across multiple years increased both implementation and performance impact;

  • Focused on fundamentals — especially capital return policies, entrenchment, and board effectiveness.

🧨 Why This Matters in 2025

Critics of shareholder proposals argue they are wasteful, confrontational, or harmful to management discretion. But Gantchev’s data suggests the opposite: When activism is data-driven and focused, it’s one of the most value-accretive tools investors have.

That makes recent attempts to raise the resubmission thresholds for proposals all the more concerning. If fewer proposals can be filed or resubmitted, many campaigns would never reach the performance-inflecting stage.
