Kenneth S. Mantel

Kenneth Mantel guides equity investors through dynamic, high-stakes engagements to achieve their investment goals, including collaborative engagement with boards and management teams, director election contests, acquisition proposals, and opposition campaigns, providing 360-degree views of challenges and opportunities, and tailored solutions that deliver results.

Ken advises leading investment funds, family offices, and high-net-worth individuals investing with public companies, inside the U.S. and internationally, on pathways to achieving their investment goals. Responsive and easy to work with, Ken knows from experience that no two clients or situations are the same, and that legal and strategic advice needs to reflect that. He works with clients to assess the situation, ascertain potential options, address legal issues, and implement a comprehensive strategic approach.

Ken has experience guiding clients through the broad spectrum of situations and issues they encounter during the course of private and public engagement with public companies and their boards and management teams, including initial stakebuilding, private discussions on strategic and governance matters, public letter-writing campaigns, director election contests, acquisition proposals, opposing company transactions or other proposals, vindication of shareholders’ rights, SEC reporting and disclosure requirements (including Schedules 13D and 13G), and general strategy.

Ken also represents corporate clients in significant securities, transactional, and general business matters, ranging from mergers and acquisitions, equity and debt financings, and initial public offerings to advising on securities laws and SEC reporting, corporate governance, business partnerships, and commercial contracts.
