Securities, M&A & Corporate Governance Litigation
In today’s market, litigators with experience in securities, corporate governance, and M&A-related (collectively, “securities litigation”) matters need to leverage their broad experience to serve as both advocate and as counsel and strategist, focused on helping clients to overcome not just a legal issue but a collective business problem. Given the frequent interplay between things such as corporate-control transactions, public offerings, activist shareholders, the use of complex derivatives and other financial instruments, bad news impacting stock performance, regulatory inquiries and investigations, and insurance coverage, strategic and tactical litigation decisions can have a wide-ranging impact on the success of a given transaction, as well as on companies, their boards, senior management, and advisors.
