Our strengths include:

  • Crisis management. When a crisis occurs, litigation, shareholder demands, and investigations often follow. We are skilled at responding effectively to the consequences of all manner of corporate traumas, such as product recalls, regulatory events, government investigations, accounting improprieties and restatements, unexpected losses or business downturns, data breaches, and whistleblower reports. Often asked to handle the multiple, overlapping proceedings that result from such events, our lawyers have a proven track record of successfully protecting our clients’ brands and reputations amid scrutiny.
  • Seeing the big picture. We have provided board-level counsel for decades. Sidley has been, and continues to be, instrumental in the development of corporate and securities law, from winning the seminal Tellabs securities fraud case in the United States Supreme Court to defeating class certification and enforcing exclusive forum selection and arbitration bylaws today. The diversity of our lawyers’ experience and backgrounds — from first-chairing securities class action jury trials, to negotiating complex corporate governance settlements, to conducting investigations in response to shareholder demands — enables us to offer valuable insight that helps clients solve their most urgent legal and business matters.
  • Focusing on individual needs. Our lawyers have a deep understanding of the challenges particular to our clients’ industries and are adept at drawing on the knowledge and experience of Sidley’s other practices to create a tailored, multidimensional response. We craft strategies to achieve each client’s goals, whether that is negotiating an early resolution or fighting through trial and appeal, if necessary. We also pride ourselves on our success in helping clients avoid litigation entirely.
  • Regulatory interface. We are especially well-suited to handle matters involving both regulatory and litigation components. Our lawyers have substantial experience with virtually every subject investigated by the SEC and other governmental agencies, including financial accounting fraud, disclosure and reporting irregularities, stock option backdating, insider trading, broker-dealer trading and operations, IPOs and other offerings, hedge fund conduct, sales of unregistered securities, trading irregularities, and Foreign Corrupt Practices Act issues. In litigation matters with a significant regulatory interface, we offer our clients coordinated and complete solutions that are fully integrated into their larger business objectives. For example, in representing life sciences companies in shareholder litigation, we work collaboratively with our cutting-edge Food, Drug, and Medical Device Regulatory practice in order to provide clients with comprehensive representation.
  • Long-standing relationships with D&O insurers. Sidley routinely works with all of the major D&O insurers and is panel counsel for the market-leading carriers, including AIG and Chubb. Our close relationships with these insurers reflect their confidence in our ability to effectively and vigorously represent insureds. We also work closely with insurance brokers, and serve as D&O panel counsel for Marsh.

Representative matters

  • Successfully represented FUJIFILM Holdings Corporation in connection with several litigation matters relating to a proposed US$6.1 billion merger transaction with Xerox Corp. These matters were highly publicized in the media, including in The Wall Street Journal, Bloomberg, Reuters, Fortune, and Law360.

    Prior to Sidley’s engagement in June 2018, the merger transaction had been enjoined by the Supreme Court of the State of New York, and Xerox Corp. then purported to terminate the transaction. In addition to taking an appeal from the injunction orders and defending FUJIFILM against the three class and derivative actions, Sidley filed a new lawsuit against Xerox in the Southern District of New York, alleging breach of the merger agreement. The Appellate Division of the Supreme Court of the State of New York issued a unanimous opinion reversing the trial court’s orders, vacating the injunction, and ordering the dismissal of the claims against FUJIFILM. FUJIFILM’s lawsuit against Xerox in the Southern District of New York led to a highly favorable settlement by which FUJIFILM bought out Xerox’s remaining interest in the joint venture and extracted numerous other concessions.
