Roger Cooper leads Cleary’s securities and M&A litigation practice.

He has successfully litigated more than fifty shareholder, class action and derivative actions arising out of securities, M&A, corporate governance, and other commercial disputes.

Roger is internationally recognized as a leader in corporate litigation by ranking publications including The Legal 500, Benchmark Litigation, and Chambers USA. Client testimonials attest to Roger’s reputation as a “terrific strategist, with a vast knowledge of his field of expertise,” “very talented,” “really spectacular,” “excellent and smart attorney,” who is “very detail-oriented and conscientious,” and “really understands the facts and the case law in securities matters and we can rely on his judgment and assessments.” He is “client oriented,” demonstrates “great judgment,” “has great advice as to strategy and potential settlements,” is “a very, very thoughtful guy,” and “a pleasure to work with and a terrific litigator.” Roger’s clients value his representation for “professionalism and responsiveness in the highest degree” and rely on his “thoughtful and creative” advice. He leads a team that clients describe as “very responsive and easy to work with,” and “extremely professional and creative in their work, flexible in their implementation and cooperation.” Clients turn to Roger and his team for “a very international approach and a lot of experience in cross-border matters.” In sum, “they are first-rate in terms of intellectual and legal acumen. They’re first grade in securities.”

Roger has a strong record of significant victories for his clients. He recently secured a complete victory in a billion-dollar case related to the termination of credit default swaps on behalf of Assured Guaranty after a five-week bench trial. He also recently won dismissal of a securities class action brought against International Flavors & Fragrances in connection with its acquisition of Israeli company Frutarom and secured affirmance on appeal to the Second Circuit in a significant decision addressing standing to bring securities claims. And he won a rare summary judgment victory in a securities class action on behalf of his client Allergan. Other victories include affirmance by the appellate court of key summary judgment rulings in favor of Merrill Lynch in a complex cross-border fraud claim arising out of its sale of a CDO to an Isle of Jersey investment vehicle structured by a German bank. In another recent matter, he favorably litigated and resolved Delaware section 220 books and records litigation (through trial), appraisal litigation, and post-closing merger litigation on behalf of Genting (Malaysia) in connection with its acquisition of Empire Resorts.

Companies rely on Roger to resolve complex cases with creative advice and advocacy. He has a particularly strong record of success representing foreign issuers in U.S. courts and handling matters with complex cross-border or international dimensions. His experience is enhanced by his close partnerships with Cleary’s tightly integrated global teams. He was a lead partner representing Petrobras in the largest U.S. securities class action ever brought against a foreign issuer (securing a favorable class action settlement in 2018 that received final approval in 2019), as well as in more than 35 separate opt-out individual actions; lead partner successfully representing the special committee of Synutra (China) in one of the most significant Delaware Supreme Court decisions of 2018; successfully secured dismissals in matters against foreign defendants DBS Satellite Services (YES) (Israel) and Sky Solar (China); and represented Whirlpool in merger-related litigation arising out of its sale of a Brazilian company.

Major clients include Applied Materials, Assured Guaranty, Atlantic Power, Bank of America, BNP Paribas, Citibank, Dun & Bradstreet, Baker Hughes, Google, Kindred Healthcare, Lowe’s, T-Mobile, The Raine Group, Open Text, Ryanair, Tech Data, and Temasek.

Roger’s substantial body of published work reflects his status as a thought leader in the field. He is the editor of the Law Review Series volume Mergers and Acquisitions Litigation Review, co-editor “Class Actions” in Lexology: Getting the Deal Through, and Co-Chair for the Cambridge Forum on Securities Litigation (2019-2022). Roger is the co-author of significant treatise chapters including “M&A Litigation” in Mergers & Acquisitions Review, “Derivatives Litigation in Federal Court” in Business and Commercial Litigation in Federal Court, and “Comparison with Commercial Litigation in Delaware Courts” in Commercial Litigation in New York State Courts. His analyses have appeared in numerous legal publications, and he is a frequent contributor to the Harvard Law School Forum on Corporate Governance and the Columbia Law School Blue Sky Blog. He is invited to speak on these topics regularly.

In addition to active litigations, Roger routinely advises boards, company executives, and in-house counsel in connection with deals or other corporate events. Working in close collaboration with Cleary’s corporate and transactional attorneys, Roger ensures his clients are advised of potential litigation risk at every stage.

Roger has substantially contributed to building Cleary’s award-winning Pro Bono practice. As the Chair of the firm’s Pro Bono Committee (2014-2017; 2021-current), the group received national recognition as Law360 Pro Bono Firm of the Year in 2015 and 2016, and as recipient of the 2016 ABA Pro Bono Publico Award. He has led or contributed to ground-breaking litigation for clients including the NAACP, Legal Aid Society, Human Rights First, Asian American Legal Education Defense Fund (ALDEF), and The American Civil Liberties Union (ACLU). Roger is currently a member of the board and audit committee of the New York Legal Aid Society.

Roger joined the firm in 2003 and became a partner in 2011.
