Testimonials
Collated independently by Legal 500 research team.
‘Kai Liekefett and Derek Zaba are two of the best lawyers in America. Not only because of their knowledge of the law as it relates to shareholder activism, but also because their ability to see around all dangerous corners and guide corporate strategy to the most successful outcome is second to none.’
‘The advice from the Sidley team in managing shareholder activism issues is extremely nuanced, and their communications with me, other executive officers, and directors are top-notch: very responsive, at the appropriate level of detail, and delivered always with an eye toward the specific business issues we are facing and how that impacts both the advice and the timing of actions.’
‘Derek Zaba and Leonard Wood are very responsive and also helpful in creating a record of board action in case the activists take us down a different path than the one we're trying to follow. They always have an eye toward anticipating litigation and a potential full-on proxy fight, while trying to avoid those outcomes.’
'High-quality, tailored advice. Always available. They are part of the team, not only outside advisors.'
'The team stand out for their skill, experience and practicality.'
