Occasional Activists and the Evolving Landscape of Shareholder Activism in 2025
Summary
Occasional activists—investors who are not dedicated activist funds, including institutional investors, insiders and first-time campaigners—remain a key force shaping proxy contests in 2025. After a record‑level surge in 2024, overall activism dipped slightly in H1 2025 but stayed broadly in line with long‑term averages, while the number of board seats secured by activists rose.
2024 saw 243 activist campaigns (near the 2018 record of 249). Barclays reports 129 global campaigns in H1 2025 (down from 147 in H1 2024 but near the nine‑year average). Activists won 86 board seats in H1 2025 (a 16% year‑on‑year increase), mostly via settlements. First‑time activists surged in 2024—18% of campaigns—but H1 2025 shows a pullback to levels closer to pre‑2024 years.
The piece highlights several notable 2025 occasional‑activist campaigns (Navitas, Zevra, Servotronics, AstroNova, Oportun), an uptick in CEO turnover after activist engagements, evolving regulatory pressure around Schedule 13D/13G disclosures, and growing influence (and shifts) in the proxy advisory ecosystem — including higher support rates from ISS and Glass Lewis and state‑level legal challenges to advisory practices.
Key Points
- 2024 was unusually active for occasional activists; 243 campaigns in 2024, with H1 2025 at 129 campaigns (Barclays).
- Activists secured 86 board seats in H1 2025, up 16% year‑on‑year, largely via settlements rather than proxy fights.
- First‑time activists accounted for 18% of campaigns in 2024 (up from 13% in 2023); H1 2025 shows fewer first‑timers but broadly normal levels once 2024 is excluded.
- Several high‑profile occasional activist campaigns in 2025 resulted in board changes, cooperation agreements, or influence over strategy (Navitas, AstroNova, Oportun, Servotronics, Zevra).
- C‑suite turnover after activist interventions accelerated: CEO departures within 12 months of campaigns nearly tripled in 2024 and the trend continued into 2025.
- SEC guidance on Schedule 13D/13G (Feb 2025) complicates engagement strategies and could push some institutional investors to temper public disclosures.
- Proxy advisors have become more assertive: ISS and Glass Lewis increased support for dissident nominees in H1 2025 and their backing correlated with higher win rates.
- The universal proxy card has not produced a wave of activist wins; management slates typically prevail unless activists present a compelling case supported by proxy advisors and large holders.
Why should I read this?
Short version: if you work with boards, are on the investor side, or advise companies, this matters. Occasional activists are nimble, often negotiate behind the scenes, and are driving faster leadership change. The piece gives a neat snapshot of 2025 trends—who won, how they did it, and what regulatory and proxy‑advisor shifts mean for the next proxy season. We skimmed the long report so you don’t have to.
Context and Relevance
The article is important because it frames how shareholder pressure is changing corporate decision‑making and governance: more settlements, more CEO turnover, and a more complex regulatory landscape. Boards, general counsel, investor relations and advisers need to factor in the rising influence of occasional activists, shifting disclosure risks from 13D/13G guidance, and the amplified role of proxy advisors when planning strategy and engagement ahead of the 2026 proxy season.
