Jason Halper
Vinson & Elkins LLPVinson & Elkins LLP has ‘deep industry knowledge’ in its complex commercial litigation practice, many of whom handle high-stakes securities cases. Chris Popov in Houston leads that practice, with Dallas-based Craig Zieminski and Michael Charlson in San Francisco taking the reins of the shareholder litigation and enforcement group. The firm is particularly well known for its work for clients in the energy sector, though it is increasingly involved in a broader spectrum of securities matters. Charlson is currently acting for Genius Brands International, which distributes and licenses children’s cartoon entertainment and related consumer products, in a notable securities class action. Michael Holmes in Dallas is a key figure in the group, and his recent work for EnCap Investments L.P. in derivative claims is noted. Jason Halper joined the team in New York from Cadwalader, Wickersham & Taft LLP in September 2024.
