Matthew L. Mustokoff, a partner of Kessler Topaz Meltzer & Check, LLP, is an accomplished securities and corporate governance litigator. He has represented clients at the trial and appellate level in numerous high-profile cases involving a wide array of matters, including financial fraud, market manipulation, corporate takeovers, unfair trade practices, and patent infringement. 


Matt is currently litigating several nationwide securities cases on behalf of U.S. and overseas investors. He serves as lead counsel for plaintiffs in In re Allergan Generic Drug Pricing Securities Litigation (D.N.J.), arising out of the industrywide price-fixing scheme in the generic drug market. Matt also represents shareholders in Sjunde AP-Fonden v. The Goldman Sachs Group (S.D.N.Y.), a securities fraud case implicating Goldman Sachs’ pivotal role in the 1Malaysia Development Berhad (1MDB) money laundering scandal, one of the largest financial frauds involving a Wall Street firm in recent memory. 


Matt played a major role in prosecuting In re Citigroup Bond Litigation (S.D.N.Y.), involving allegations that Citigroup concealed its exposure to subprime mortgage debt on the eve of the 2008 financial crisis. The $730 million settlement marks the second largest recovery ever in a Securities Act class action brought on behalf of corporate bondholders. Matt represented the class in In re Pfizer Securities Litigation (S.D.N.Y.), a twelve-year fraud case alleging that Pfizer concealed adverse clinical results for its pain drugs Celebrex and Bextra. The case settled for $486 million following a victory at the Second Circuit Court of Appeals reversing the district court’s dismissal of the action on the eve of trial. Matt also served as class counsel in In re JPMorgan Chase Securities Litigation (S.D.N.Y.), arising out of the 2012 “London Whale” derivatives trading scandal. The case resulted in a $150 million recovery. 


Matt served as lead counsel to several prominent mutual funds in securities fraud actions in Manhattan federal court 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 Connecticut Retirement Plans & Trust Funds v. BP plc (S.D. Tex.), a multi-district litigation stemming from the 2010 Deepwater Horizon oil-rig explosion in the Gulf of Mexico, Matt successfully argued the opposition to BP’s motion to dismiss and obtained a landmark decision sustaining fraud claims under English law on behalf of investors on the London Stock Exchange—the first in a U.S. court. Matt’s significant courtroom experience includes serving as one of the lead trial lawyers for shareholders in the only securities fraud class action arising out of the 2008 financial crisis to be tried to jury verdict. 


Prior to joining the Firm, Matt practiced at Weil, Gotshal & Manges LLP in New York where he represented clients in SEC enforcement and white collar criminal matters, shareholder litigation, and contested bankruptcy proceedings. 


Matt is a Phi Beta Kappa honors graduate of Wesleyan University. He received his law degree from the Temple University School of Law.
