Career
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.

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.

Work Highlights
Some of Lori’s notable representations include serving as lead trial counsel for:
• Brought an action in Delaware Court of Chancery against primary health care provider Cano Health, Inc. whose stock price plummeted by 92% in the years following its IPO. In 2023, Olshan clients Elliot Cooperstone and Lewis Gold (together with Barry Sternlicht, plaintiffs), former directors of Cano and 35% shareholders, filed a complaint and motion for expedited proceedings against the company and its board in the Delaware Court of Chancery, seeking an injunction to reopen the company’s window for director nominations and shareholder proposals due to material events that occurred and material information that came to light after the nomination window closed. A withhold campaign was launched in tandem with the litigation. Plaintiffs alleged the company and its affiliates had engaged in a series of conflicted transactions with the CEO and members of his immediate family and that after the nomination window closed, the balance of the board formed a special committee intentionally designed to usurp the power of the full board, which precipitated Plaintiffs’ campaign. After securing a motion to expedite, Olshan’s team completed discovery in less than three weeks, including seven depositions. The parties submitted approximately 250 exhibits in advance of the hearing. Although the court denied Plaintiffs’ motion, finding that under Delaware law, the alleged conduct did not constitute “fundamental changes in the operation and management” of the company, the combined efforts of the litigation and withhold campaign were successful. At the annual meeting, over 80% of shareholders voting withheld votes from the company’s nominees for re-election. Further, the conflicted CEO was forced to step down effective immediately.
• Olshan client Strategic Investment Opportunities LLC (SIO) brought two proceedings in the Delaware Court of Chancery in its effort to nominate a slate of directors at the annual meeting of Lee Enterprises, Inc. (Lee). In the first litigation, SIO alleged breach of fiduciary duty against the Lee board and sought expedited injunctive relief. In less than a week, after Olshan completed expedited discovery, seven depositions, expert reports, and pre-trial briefs, the trial was held. The court found for the defendants, finding that SIO had not complied with Lee’s advance notice bylaws. Although SIO did not prevail on its claim, the case is important because it clarifies the standard of review applicable to a board’s conduct in a contested election. In the second litigation (Lee II), SIO challenged Lee and the board’s use of the plurality voting standard at the upcoming annual meeting election, alleging the nominations were invalid, a position the court upheld. Thereafter, following briefing and oral argument, the court denied SIO’s motion to expedite and for a temporary restraining order, holding that SIO could pursue its claims following the annual meeting. The court reasoned that SIO had stated colorable claims that the application of a plurality voting standard where only incumbents were running was inconsistent with the bylaws but did not grant the relief sought in view of the imminent meeting date. To our knowledge, Lee II is the first time the court has interpreted a bylaw requiring a majority voting standard in an uncontested election.
• Successfully represented Kingstown Partners Master Ltd. (Kingstown) in an §1782 application to the Southern District of New York seeking discovery from multiple corporate respondents to support a Cayman Islands appraisal proceeding in connection with a $2.7 billion merger. Kingstown and other dissenting shareholders alleged multiple conflicts of interest In re Kingstown Partners Master Ltd., No. 21-MC-691-LTS (S.D.N.Y. April 8, 2022). The 1872 application was necessary because Cayman courts lack jurisdiction to order discovery from foreign-domiciled third parties in appraisal proceedings. The court (Hon. L. Swain) rejected the respondents arguments that Kingstown was seeking to circumvent foreign restrictions on evidence and that the discovery requests were unduly broad and irrelevant to the fair value determination and found in our client’s favor, granting all written discovery Kingston sought. This decision has important precedential value given the increasing frequency of litigation over international business transactions, and the increasing potency of § 1782 as a tool for litigants.
