M&A litigation: defense

Within: M&A litigation: defense

Paul, Weiss, Rifkind, Wharton & Garrison LLP is β€˜a premier firm for M&A defense, highly respected and very professional’ and clients praise the litigators for β€˜their vigor, their insight and their experience’. Stephen Lamb in Wilmington, who served as Vice Chancellor in the Delaware Court of Chancery, is one of the firm’s β€˜truly exceptional lawyers’ along with New York partners Geoff Chepiga, Richard Rosen, Andrew Gordon and Daniel Toal. Chepiga and Toal successfully resolved several cases for Air Methods Corporation arising from its $2.5bn sale to affiliates of American Securities LLC, in which shareholders challenged the going-private transaction. Lamb and Gordon were part of a large team that acted for the defendants in one of the most closely watched M&A litigation suits of 2017, which concerned the $5.3bn acquisition of medical diagnostic company Alere by Abbott Laboratories. Abbott filed suit against Alere in an attempt to terminate the deal but the final settlement saw the transaction conclude for a slightly reduced price per share.

Securities litigation: defense

Within: Securities litigation: defense

β€˜Outstanding firm’ Paul, Weiss, Rifkind, Wharton & Garrison LLP in New York is β€˜without peer on all criteria’, according to one client. β€˜Fabulous lawyer’ and firm chair Brad Karp β€˜may be the best lawyer in the US’, says another. β€˜We trust his judgment implicitly’ say clients of Daniel Kramer, who has β€˜great practical business sense, unparalleled legal experience, a prodigious work ethic and a longstanding reputation for both ethical and intellectual integrity’. β€˜Truly exceptional lawyer’ Andrew Ehrlich is β€˜particularly impressive’ and co-chairs the securities litigation group with Susanna Buergel and Audra Soloway. Karp and Buergel scored an appellate victory for Citigroup in an $800m investor claim that alleged fraudulent misrepresentation of its exposure to subprime mortgage assets. Leading light Richard Rosen and Washington DC-based rising star Jane O’Brien succeeded in having the majority of claims against Alere Inc dismissed in cases alleging that the company improperly recognized revenue for subsidiaries in Africa and China, and failed to disclose the need to recall diagnostic products. Geoff Chepiga and Washington DC-based Charles Davidow are also recommended.
