With ‘top tier legal talent’ throughout its New York and Washington DC offices in particular, including former US government prosecutors and regulators, A&O Shearman is well-positioned to defend corporates, boards of directors, special committees, and individuals in their most pressing private class actions as well as in government-initiated investigations/enforcements. The financial services sector remains a particularly fecund source of work, including as it relates to market manipulation and rate-fixing cases, as well as in the defense of banks for alleged securities-related infractions in their role as underwriters on public company offerings. Adam Hakki remains central to much of this, leveraging deeply engrained relationships with many of Wall Street’s finest to good effect. In addition, Hakki maintains a thriving public company practice, both in the context of Securities Act cases, as well as on shareholder derivatives and M&A litigation. Daniel Lewis and Agnès Dunogué are also very well-versed at handling securities cases for large financial institutions, while Washington DC-based partner Lyle Roberts excels at handling securities-related investigations and enforcement actions before the SEC. In San Francisco, the ’responsive, focused, strategic and experienced’ Daniel LaGuardia is well-regarded by clients from across a range of industries, including technology, for his skill at handling securities litigation matters, and his prowess at advising on corporate governance-related matters as well as for his overarching commercial litigation smarts. All named practitioners are based out of New York, unless otherwise indicated.
