Lori Marks-Esterman is among the nation’s leading shareholder litigators and corporate governance experts. She is the head of Olshan’s Shareholder Activism Litigation Practice, represents investors and other stakeholders in capital markets matters and other complex commercial disputes. She is a seasoned trial attorney proficient in handling capital markets litigation and corporate governance disputes.

Hedge funds, private equity companies, shareholder activists and other public and private entities entrust their most challenging litigation matters to Lori. She litigates and has secured critical wins in multibillion-dollar litigation matters in influential jurisdictions in securities-related litigation, M&A disputes and cases involving corporate governance, shareholder activism, breach of fiduciary duty, D&O liability and breach of complex, commercial agreements.

Lori also advises investors, stockholders and directors on the full range of governance issues, including fiduciary duties, conflicts of interest, board and committee structure, shareholder and director rights and duties, proxy contests and compliance with governance best practices.

Lori’s sharp litigation skills, coupled with her corporate governance expertise, allow her to assess risk, define strategy and devise business solutions that deliver results. Investors in private and public companies routinely rely on Lori in high-profile contentious activist matters. She has served as lead trial counsel in several highly sophisticated matters tried in the Delaware Court of Chancery and New York courts.

Lori also has significant experience in cross-border matters, utilizing Section 1782 cases to obtain critical evidence in the U.S. for use in foreign litigation. Working closely with foreign co-counsel, Lori develops case and discovery strategies for foreign disputes. Among these, she represented IsZo Capital LP in the Southern District of New York in a $170 million private placement dispute that culminated in what various media called “an epic” victory. She also recently secured a multibillion-dollar precedent-setting win on a Section 1782 application that sought discovery from multiple corporate respondents in a $2.7 billion merger.
