M&A/corporate and commercial > Shareholder activism Tier 1

Clients appreciate the ‘extremely nuanced‘ advice from the team at Sidley Austin LLP, which handles the gamut of shareholder activism matters for board members. One client dubs leadership duo Kai Liekefett and Derek Zaba ‘two of the best lawyers in America‘, lauded for ‘their ability to see around all dangerous corners and guide corporate strategy to the most successful outcome‘. Liekefett is based in New York and focuses exclusively on shareholder activism and takeover defense. In two decades of practice, he has worked in the UK, Germany, Hong Kong, and Japan, and is one of the most prolific advisors on proxy contests, including a high percentage of the market’s late-stage contests. Zaba, who is based at the Palo Alto office, also fully dedicates his practice to shareholder activism and has quickly established himself as one of the go-to lawyers in the field. Beth Berg (Chicago) is a senior figure with broad corporate law expertise, younger partners Leonard Wood (Houston) and Jessica Wood (New York) are also active in the shareholder activism space, and the New York office was further bolstered in January 2024 by the promotion to partner of Reuben Zaramian, who focuses on shareholder activism and corporate governance.
