The team at Cleary Gottlieb Steen & Hamilton is adept at tackling shareholder suits tied to M&A deals and allegations of breaches of fiduciary duties by directors and officers, with experience in pleading cases before state and federal courts, including the Delaware Court of Chancery. Leading the practice out of the New York office is Roger Cooper, who has a strong track record for corporate defendants in shareholder class actions, derivative actions tied to both mergers and perceived failures of governance. Currently he is defending T-Mobile USA in a case brought by a stockholder alleging that certain officers breached fiduciary duties in the 2020 merger with Sprint. Another member of the core team is Mark McDonald, who handles both securities and shareholder litigation. In addition to assisting Cooper on the T-Mobile matter, McDonald also represents OCI N.V. in relation to a claim brought by joint venture partner Proman, following the former’s sale of its methanol business.
