“The U.K. remains the primary driver of public-facing engagement in Europe, with other European markets increasingly witnessing similar strategies when behind-the-scenes efforts fail,” said Josh Black, Editor-in-Chief, Diligent Market Intelligence. “Activism in Europe runs the full gamut from hostile media campaigns to more private engagements but there is no doubt that boards should prepare for anything in what looks likely to be a very busy annual meeting season.”

Produced in association with White & Case, a global law firm, the report reveals that while smaller-cap companies accounted for nearly 70% of all U.K. activism, large-cap campaigns were largely led by prominent U.S. activists who are increasingly turning to the European market for value opportunities.
