Alternative Asset Management: We have a world-leading practice advising private equity funds, hedge funds, credit funds and other alternative asset management firms. Our litigators have handled some of the most significant litigation arising from fundamental transactions, corporate governance disputes, the financial meltdown, the mortgage crisis, industry-shaping mergers, and shareholder litigation in response to large going-private transactions.

Life Sciences: We have cornered the market in representing life sciences companies in complex shareholder, securities and derivative litigation. We have had unparalleled success litigating securities claims against life science companies; the cases we have won for life science companies in recent years have set the standards used to evaluate disclosure claims against life science and big pharma companies. Drawing on this experience, we regularly counsel clients about difficult and important SEC disclosure decisions involving events such as the reporting of clinical trials results or dealing with conflict of interest issues.

Mutual Funds: We are a leading firm advising the mutual fund and registered ’40 Act industry, and have represented clients in some of the most significant securities law matters, including those related to the timing of regulatory disclosure and other issues common to the mutual fund industry. Particularly of note is that we were the first firm ever to secure summary judgment in “excessive fee” cases, and we established in the U.S. Supreme Court the legal standard against which Section 36(b) liability is now measured (Jones v. Harris Associates). Drawing on our large investment company and mutual fund practice, the firm’s litigators have both extensive experience in mutual fund litigation and enormous bench-strength to draw upon – we have taken multiple cases to trial in the mutual fund space.

Public Companies: We also serve as general or special counsel to more than 100 public companies and pride ourselves on continuously delivering successful results to these clients in some of the most high-stake cases. In the areas of public and private securities offerings and acquisitions, we have been responsible for establishing important precedents that substantially limit the scope of claims against issuers and their directors and officers, shrinking the class of possible claimants and claims. We have represented boards of directors and independent committees, investment bankers, and management teams in both friendly and hostile takeovers as well as highly expedited litigation and litigation involving fiduciary duties and responsibilities.

In addition to our breadth of experience in defending our clients in litigation, we also have equally extensive experience advising them on managing litigation risk in transactional settings. Working hand-in-hand with our clients’ senior executives and boards of directors, as well as with our corporate colleagues, we focus on counseling our clients on ways to avoid or minimize potential litigation exposure. Our success in this area stems from our ability to conduct thorough, but discreet, investigations to the satisfaction of our clients and their boards, and to obtain the resolution of regulatory or government investigations well before any enforcement proceedings or other actions are filed.

  • Canada Goose Holdings Inc. and Bain Capital. Successfully defended Canada Goose Holdings, Inc., its current CEO and CFO, as well as Bain Capital, in a federal securities action regarding the company’s disclosures concerning inventory and consumer demand. The securities class action was filed in the Southern District of New York against Canada Goose and its officers under Section 10(b) of the Exchange Act. The plaintiffs also filed claims against Bain Capital, Canada Goose’s majority stockholder. The court granted our motion to dismiss.
  • Keurig Green Mountain, Inc. Lead counsel in securing complete dismissal of a federal securities class action challenging statements concerning the company’s introduction of a new product. After prevailing on a motion to dismiss the plaintiffs’ first consolidated complaint, the plaintiffs agreed to voluntarily dismiss the action with prejudice following a hearing on Ropes & Gray’s motion to dismiss a second amended complaint and motion for sanctions. Also lead counsel defending KGM in three sets of securities fraud and derivative actions and related SEC investigation regarding alleged accounting improprieties. Successfully secured a Second Circuit affirmation of the dismissal in one securities action, an appeal was withdrawn in another and convinced the SEC to close its four-year long inquiry without recommending any enforcement action against the company or its current or former employees.
  • Oxbow Carbon & Mineral Holdings, Inc. & William I. Koch. Secured a victory in the Delaware Supreme Court on behalf of industrialist William I. Koch and certain of his affiliated investment vehicles, who together compose the majority stakeholders of Oxbow Carbon LLC, seeking to prevent a forced sale of Oxbow Carbon by its minority members. The case was initially tried in the Delaware Court of Chancery, which found that Mr. Koch had advanced the only logical interpretation of the LLC Agreement—which operated to prevent a forced sale under current market conditions—but that an implied covenant existed to reverse that result. In an en banc decision, the Delaware Supreme Court found that the plain language of the LLC Agreement controlled and reversed the Chancery Court’s im­plied covenant holding, vindicating Mr. Koch’s position as argued by Ropes & Gray in the Supreme Court.
  • ProShares. Secured the dismissal of all claims in a consolidated securities class action against ProShares and several individual defendants. ProShares is one of the world’s largest sponsors of leveraged and inverse exchange-traded funds (ETFs), and the suit related to losses in ProShares’ “short volatility” fund during a one-day spike in market volatility. The Second Circuit affirmed the dismissal.
  • Bain Capital. Represented in connection with Toshiba Corp.’s sale of its semiconductor business to a group led by Bain in a transaction valued at approximately $18 billion - understood to be the largest Japanese deal since 2011, as well as both the largest private equity and leveraged finance deal ever seen in Asia. The transaction was successfully completed despite Toshiba’s U.S. venture partner, Western Digital, seeking to block the sale through litigation.
  • Stemline Therapeutics. Secured complete dismissal of a securities class-action lawsuit brought against the clinical-stage biopharmaceutical company and its officers and directors under section 10(b) of the Exchange Act.
