Josh Materese, a Partner at Kessler Topaz, advises institutional investors across the globe on matters arising from securities fraud, shareholder-rights violations, market manipulation, anticompetitive conduct, and other corporate misconduct.

Josh represents and counsels public pension funds, sovereign wealth funds, asset managers, mutual funds, hedge funds, and other institutional investors throughout the loss-recovery process, from portfolio monitoring, case identification, and legal evaluation through the development and implementation of litigation and recovery strategies. He advises investors on whether and how to participate in U.S. and non-U.S. proceedings, including seeking appointment as lead plaintiff, pursuing individual or opt-out claims, participating in collective actions and arbitrations, and evaluating other available recovery mechanisms. His practice spans the United States, Europe, and Asia.

($290 million), JPMorgan Chase & Co. ($150 million), HP Inc. ($100 million), and Wells Fargo & Co. ($85 million).

Josh has also represented institutional investors pursuing individual claims in some of the largest securities litigations of the past two decades. In this capacity, he served as counsel to dozens of sovereign wealth funds, asset managers, and mutual funds in In re Petrobras Securities Litigation (S.D.N.Y.), In re Perrigo Co. Securities Litigation (D.N.J.), and In re Teva Pharmaceuticals Securities Litigation (D. Conn.), helping those investors achieve hundreds of millions of dollars in recoveries.
