Shareholder Activism


Unique insight into shareholder engagement

"White & Case's uniqueness and value really shone through… Your cadre of activist investor work is unlike anything I have seen from other law firms." Leading proxy advisor

Active shareholder engagement can take many forms, from private discussions between shareholders and companies to public, hostile campaigns. One thing is clear, however, activists are enjoying increased global influence, even in jurisdictions where historically activism has been negatively received.

As a regular advisor to both public companies and activists (White & Case was ranked #1 law firm in the FY 2020 Bloomberg Activism League Tables for both company and activist side work), we are uniquely placed to give clients valuable tactical and strategic insight. Our dedicated shareholder activism practice, comprising a core team of public M&A, public company advisory, litigation, tax, capital markets and employment specialists, understand what is at stake for our clients, both public companies and engaged shareholders. We pride ourselves in being able to develop innovative and bespoke solutions to guide our clients to a successful outcome.
