In a climate marked by geopolitical uncertainties and a tepid mergers and acquisitions (M&A) environment, shareholder activism in the U.S. remains resilient. The year 2025 saw a notable uptick in activism campaigns, with 313 initiated against U.S. companies, surpassing the 302 campaigns from the previous year. Conversely, global activism saw a slight decline, with 583 campaigns launched compared to 593 in 2024. This trend highlights a growing fervor for activism within the U.S. market, despite the global slowdown.

M&A Campaigns on the Rise
The second half of 2025 marked a resurgence in M&A-focused activism. After a sluggish start, the number of campaigns targeting U.S. companies rose to 40, up from just 25 in the first half of the year. Activists increasingly sought to dismantle large conglomerates, pressuring firms to divest non-essential assets or consider sales. This strategic shift underscores a broader trend, particularly in sectors like banking and energy, where consolidation remains a key focus.
Settlements Prevail in Activist Campaigns
While aggressive proxy fights have become costly—averaging approximately $7.24 million for campaigns that proceeded to votes in 2025—most activist campaigns opted for negotiated settlements. In fact, over 90% of U.S. board seats acquired by activists were obtained through agreements rather than shareholder votes. Nevertheless, for those campaigns that did engage in direct confrontations, activists had a notable success rate, securing at least one seat in 40% of contested elections in 2025, compared to a 28% success rate in 2024.
Year-Round Activism: A New Norm
The concept of a distinct proxy season is fading, as activism has evolved into a year-round endeavor. Campaigns no longer cluster around traditional nomination periods; instead, off-cycle initiatives employing advanced multimedia strategies are gaining traction. Activists are increasingly launching surprise campaigns without prior private engagements, which has changed the dynamics of shareholder interactions. “Withhold” campaigns, where shareholders are urged to vote against directors, gained significant momentum in 2025, showcasing the effectiveness of direct and immediate appeals.
Shifting Regulatory and Political Landscapes
As regulatory frameworks and political pressures shift, the landscape of shareholder activism faces new uncertainties. These changes may lead to unpredictable voting outcomes in contested elections and M&A scenarios. Companies may need to adapt their investor engagement strategies, expanding outreach to diverse investor groups and recalibrating communications with index funds and retail shareholders. Activists, emboldened by this unpredictability, may feel more inclined to initiate campaigns and resist settlement negotiations.
Importance of Preparedness and Engagement
For corporate boards, the evolving dynamics necessitate a proactive approach. They must remain vigilant and prepared for off-cycle challenges, maintaining ongoing dialogues with key investors. This continuous engagement is critical, especially concerning non-core assets or strategic options that could be misinterpreted.
Regular board education and preparedness initiatives are essential. Boards should consistently evaluate their structures and compositions to ensure that each member contributes unique and critical skills. A cohesive board that presents a unified front is better equipped to navigate the complexities of increasingly sophisticated activist campaigns.
