Fried, Frank, Harris, Shriver & Jacobson LLP scores ‘A-plus on all fronts’, according to one client. Global litigation chair James Wareham in Washington DC leads on securities matters. His highlights from 2017 included advising pharmaceuticals company Perrigo in a class action - Roofers’ Pension Fund v Joseph Papa, et al - which alleged that the company inflated its share price by, among other things, failing to disclose integration problems following the acquisition of Omega Pharma, by overstating organic growth and via anti-competitive pricing in its generics division. The firm has a strong practice in New York, where William McGuinness and the ‘responsive and extremely knowledgeableStephen Juris (who is ‘adept in his development of strategies and is realistic about possible outcomes’) scored a victory for underwriters of MaxPoint Interactive’s 2015 IPO, when all claims were dismissed.
