Joshua Materese

Josh Materese, a Partner of the Firm, is an experienced and trusted securities litigator. He devotes his practice almost entirely to advising and representing institutional and individual investors in class or direct actions arising from fraud, market manipulation, or other corporate misconduct. Josh currently serves as one of the lead trial attorneys in pending securities class actions involving General Electric, Kraft-Heinz, Goldman Sachs, and Boeing, and in direct actions involving Teva Pharmaceutical and Perrigo Co. During his career, Josh has helped clients recover substantial monetary losses, including most recently In re Allergan, Inc. Proxy Violation Securities Litigation, No. 14-cv-02004 (C.D. Cal.) ($290 million recovery), In re JPMorgan Chase & Co. Sec. Litig., No. 12-cv-03852 (S.D.N.Y.) ($150 million recovery); Lou Baker v. SeaWorld Entertainment, Inc., et al., No. 14-cv-02129 (S.D. Cal.)

Josh also successfully litigated claims on behalf of over 100 U.S. and international institutional investors in direct actions against Brazil’s state-run oil company, Petrobras, arising out of a decade-long bid-rigging scheme—the largest corruption scandal in Brazil’s history.

In addition to his direct litigation responsibilities, Josh advises the Firm’s institutional clients on potential claims they may have in shareholder litigation. He is one of the partners at the Firm responsible for client relations and outreach in the U.S., and assists with overseeing Kessler Topaz’s proprietary portfolio monitoring and claims filing service, SecuritiesTracker.

Josh also maintains an active pro bono practice. He serves as Co-Chair of the Firm’s Pro Bono Committee and frequently represents clients referred to the Firm on matters concerning federal disability benefits, felony pardons, and wrongful convictions.
