Proxy Advisor Role in Activist Campaigns

Proxy advisors—primarily ISS (Institutional Shareholder Services) and Glass Lewis—wield outsized influence in contested proxy fights. These firms analyze board proposals and activist campaigns, issuing recommendations that institutional shareholders largely follow. Activists who win ISS or Glass Lewis endorsement often win the vote; those who lose their backing face near-certain defeat. Understanding how proxy advisors evaluate campaigns is essential for activists and targeted companies alike.

The Proxy Advisor Duopoly and Its Power

Institutional investors—pension funds, mutual funds, endowments, hedge funds—collectively own roughly 60–70% of US public company stock. These institutions must vote their shares but often lack the resources to independently analyze every ballot issue. They delegate voting recommendations to proxy advisory firms.

ISS and Glass Lewis dominate this role. ISS advises approximately 1,800 institutions managing $120+ trillion in assets. Glass Lewis advises roughly 1,400 institutions. Together, they effectively control shareholder voting outcomes in contested proxy battles.

The empirical evidence is stark. Studies show ISS recommendations are followed 95%+ of the time. When ISS recommends a slate of activist directors, those directors typically win. When ISS backs incumbent management, activists typically lose—even if they have sound strategic arguments.

This concentration of power arose partly by design (institutions chose to delegate) and partly by network effects (larger investors needed larger advisor networks, which drove consolidation). The result is a system where two private firms function as unelected gatekeepers for corporate democracy.

How Proxy Advisors Evaluate Activist Campaigns

When an activist campaign emerges, proxy advisors typically conduct a deep analysis over 4–8 weeks:

Board candidate evaluation: ISS and Glass Lewis examine the activist’s proposed directors. Are they independent? Do they have relevant industry experience? What is their track record on past boards? A candidate with solid operational or financial expertise often wins backing. A candidate with conflicts of interest (even minor ones) may sink the entire campaign.

Strategic merit: The advisors assess whether the activist’s proposed strategy (cost cuts, M&A, capital allocation changes) makes sense for the company. Does it align with industry trends? Does it exploit genuine operational or financial weaknesses, or is it opportunistic? Management’s response matters too. If management can credibly explain why they’re already pursuing the activist’s goals or why the strategy is flawed, advisors may side with incumbents.

Track record: Advisors evaluate the activist’s past campaigns. Serial activists with strong returns at prior companies earn credibility. First-time activists or those with failed campaigns face skepticism.

Company performance and necessity: Companies with weak boards and poor stock price performance are more vulnerable. Companies with strong governance and solid returns are stickier. The weaker the incumbent’s record, the lower the bar for the activist to clear.

Fallback governance: Proxy advisors also consider whether the company has already adopted some of the activist’s proposals or governance improvements. If management is responsive, the urgency of an activist-forced change diminishes.

The proxy advisors publish detailed reports 1–2 weeks before the shareholder meeting, typically after the company and activist have had a chance to submit materials. These reports are read by institutional investors and heavily influence how they vote.

The Activist Playbook: Securing Proxy Advisor Support

Successful activists spend as much time courting proxy advisors as they do courting large shareholders. The sequence is roughly:

1. Pre-announcement engagement: Before the campaign goes public, activists often reach out to ISS and Glass Lewis (and sometimes directly to major shareholders) with their thesis. They build a dossier: detailed analyses, board candidate CVs, financial models, and operational plans.

2. Clean candidate slate: Activist campaigns live or die on board candidates. The best activists identify truly independent, high-caliber candidates—often retired operating executives or recognized experts—with spotless credentials and no conflicts. Mediocre or ethically questionable candidates doom the campaign.

3. Compelling narrative: The activist must articulate a clear, defensible thesis for change. “The company is undervalued and the board is complacent” is too vague. “The company’s cost structure is 10% above peers, and we have identified $200M in specific savings without sacrificing growth” is credible.

4. Responsive company: If the target company responds thoughtfully (e.g., they initiate board refreshment, engage the activist privately, make some concessions), advisors may soften. If the company goes nuclear (personal attacks on the activist, dismissive responses), advisors may turn against them.

5. Market conditions: In bull markets or when the company is performing well, advisors favor stability. In downturns or when the company is underperforming, advisors favor change.

The Incumbent Rebuttal

Targeted companies have parallel obligations. They must file their own analysis with proxy advisors, respond to activist allegations, and articulate a case for why their strategy is sound or why the activist’s candidates are unqualified.

Strong incumbents:

• Point to genuine business progress or turnarounds already underway.
• Highlight board refreshment or governance improvements already executed.
• Raise questions about activist conflicts (their activist history, fee structure, motivation to push for near-term gains over long-term value).
• Document candidate weaknesses (lack of relevant experience, past failures, undisclosed conflicts).

Weak incumbents often make the proxy advisors’ jobs easier by failing to respond thoughtfully, making overheated personal attacks, or having demonstrable governance problems (e.g., a board with no independent directors, weak audit processes).

The Mechanics of Voting

Once the proxy advisors issue recommendations, voting typically plays out as follows:

• Say-on-pay and ordinary ballots: ISS and Glass Lewis recommendations on executive compensation or routine matters usually carry, following their vote guidance.
• Contested director elections: If ISS recommends the activist slate, typically 60–80% of shareholders vote for them, often enough to win. If ISS backs management, the activist candidates usually win fewer than 40% of votes.
• Tie scenarios: Rare but possible. If ISS and Glass Lewis split, or if one is neutral, the outcome can swing on other factors (large activist shareholders’ own voting, public campaigns, shareholder sentiment).

Regulatory Scrutiny and Limits

The SEC and Congress have questioned proxy advisor power. Concerns include:

• Conflicts of interest: Both ISS and Glass Lewis also provide consulting services to companies and investors, raising potential conflicts.
• Lack of transparency: Proxy advisors don’t fully disclose their methodologies or allow public input.
• Limited appeal: Companies can challenge recommendations, but the appeals process is slow and opaque.

Recent SEC guidance has loosened rules slightly, permitting companies to discuss draft proxy advisor reports with advisors before final publication. But the fundamental dynamic remains: ISS and Glass Lewis can make or break a campaign.
