Boardroom Advisory Firms in Activist Defense: Market Landscape

Shareholder activism reached its highest level since 2018 in 2024, with Barclays counting 243 global campaigns and 155 in the U.S. alone. Universal proxy cards, introduced in 2022, have reshaped board contests by making it easier for dissidents to nominate individual directors. The result: a booming market for specialized activist defense advisors across multiple disciplines.

The Activist Defense Ecosystem

Effective activist defense rarely involves a single advisor. Public companies typically assemble a team spanning four categories:

Investment Banks & Strategic Advisors
Firms like Evercore, Goldman Sachs, PJT Partners (via its CamberView acquisition), and Lazard advise on strategic alternatives, valuation defense, and investor engagement. Evercore is widely recognized as the leading independent activism defense advisor globally.
Proxy Solicitors
Innisfree M&A has held the #1 global proxy solicitor ranking in Bloomberg's league tables for six consecutive years through 2024. MacKenzie Partners, Okapi Partners, Morrow Sodali, and D.F. King (an Equiniti company) round out the top tier.
Legal Advisors
Sidley Austin ranked #1 for company defense in FactSet's 2024 league tables with a record number of engagements. Vinson & Elkins took #2, followed by Latham & Watkins. Other prominent defense firms include Paul, Weiss, Paul Hastings, Cravath, and Goodwin.
Strategic Communications & IR
Joele Frank has ranked #1 as Shareholder Activism Defense IR/PR Advisor since 2019 per Bloomberg, with over 1,000 activism defense engagements since 2000. FGS Global is another leading communications advisor, with an integrated global team of specialists.

Choosing the Right Advisory Team

Corporate secretaries and general counsels evaluating activist defense advisors should consider:

  • Conflict policy — Some firms advise both companies and activists (dual-hat), while others like Joele Frank are conflict-free, exclusively advising companies
  • Industry specialization — Activism patterns differ significantly between sectors; advisors with relevant sector experience can anticipate activist playbooks
  • Track record in settlements vs. proxy fights — Given that settlements dominate outcomes, negotiation capability matters as much as courtroom or ballot-box expertise
  • Global coverage — Cross-border campaigns require coordinated local counsel and solicitation in multiple jurisdictions
