A&O Shearman‘s securities litigation practice has a strong record in acting for the world’s largest underwriting banks, and has further broadened its client base to include big-name public companies, notably in the technology sector. The work of San Francisco-based partner Daniel LaGuardia for Uber Technologies in a securities class action arising from its 2019 IPO is a prime example. The practice is led from New York but standout litigator Adam Hakki and global litigation practice group Richard Schwed . Hakki is widely acknowledged as a leading practitioner in this area, and his victory for Paramount Global in a securities class action litigation arising from the historic collapse of Archegos Capital Management is a standout case from the past year. Also in New York, Daniel Lewis and up-and-coming partner Agnès Dunogué are highly visible in the market, as is regulatory enforcement and securities litigation specialist Lyle Roberts  in Washington DC. Houston-based Mallory Brennan and Samuel Cooper, and former federal prosecutor Patrick Hein in San Francisco also plays a key role in securities fraud cases. Patrick Robbins left the firm in 2023 to join the DOJ.
