Jeremy A. Lieberman is Pomerantz’s Co-Managing Partner with Patrick Dahlstrom. Mr. Lieberman became associated with the Firm in August 2004, and became a partner in January 2010. He has been honored as a 2016 and 2017 Super Lawyers® “Top-Rated Securities Litigation Attorney,” a recognition bestowed on no more than 5% of eligible attorneys in the New York Metro area, and as a 2018 Super Lawyer®.

In 2016, The Legal 500 recognized Mr. Lieberman's legal acumen, stating: 

“In New York, Jeremy Lieberman is ‘super impressive – a formidable adversary for any defense firm.”

Mr. Lieberman led the litigation in In re Petrobras Sec. Litig., a closely-watched securities class actions arising from a multi-billion dollar kickback and bribery scheme involving Brazil’s largest oil company, Petróleo Brasileiro S.A. – Petrobras, in which Pomerantz was sole Lead Counsel. The biggest corruption in the history of Brazil has ensnared not only Petrobras' former executives but also Brazilian politicians, including former president Lula da Silva and one-third of the Brazilian Congress.

In January 2018, Mr. Lieberman achieved a historic $3 billion settlement for the Class. This is not only the largest securities class action settlement in a decade, but is the largest settlement ever in a class action involving a foreign issuer, the fifth-largest class action settlement ever achieved in the United States, and the largest settlement achieved by a foreign lead plaintiff.

Mr. Lieberman also secured a significant victory for Petrobras investors at the Second Circuit Court of Appeals, when the court rejected the heightened ascertainability requirement for obtaining class certification that had been imposed by the Third Circuit Courts of Appeals. The ruling will have a positive impact on plaintiffs in securities fraud litigation.

Mr. Lieberman is Lead Counsel in a putative securities class action that alleges Barclays PLC misled institutional investors about the manipulation of the banking giant’s so-called “dark pool” trading systems in order to provide a trading advantage to high-frequency traders over its institutional investor clients. This case turns on the duty of integrity owed by Barclays to its clients. In November 2017, he achieved precedent-setting victories for investors, when the Second Circuit Court of Appeals held that direct evidence of price impact is not always necessary to demonstrate market efficiency to invoke the presumption of reliance, and that defendants seeking to rebut the presumption of reliance must do so by a preponderance of the evidence rather than merely meeting a burden of production.

Mr. Lieberman has had an integral role in a number of high-profile securities class and derivative actions, including Comverse Technology Sec. Litig., in which he and his partners achieved a historic $225 million settlement on behalf of the Class, which was the second-largest options backdating settlement to date.

Mr. Lieberman also serves as Lead Counsel in a number of the most high-profile securities class actions pending in the U.S. courts, such as In re Mylan N.V. Sec. Litig., In re Perrigo Co. Sec. Litig., In re Yahoo!, Inc. Sec. Litig. and In re Fiat Chrysler Automobiles N.V. Sec. Litig

Mr. Lieberman serves as Interim Class Counsel on behalf of a class lenders and financial institutions litigating claims arising out of the London Interbank Offered Rate (“LIBOR”) rate rigging scandal. He was Lead Counsel in In re Medicis Corp. Sec. Litig., in which the court approved an $18 million settlement, and is Lead Counsel in a number of the Firm’s other litigations.

In In re China North East Petroleum Corp. Sec. Litig., Mr. Lieberman achieved a significant victory for shareholders in the United States Court of Appeals for the Second Circuit, whereby the Appeals Court ruled that a temporary rise in share price above its purchase price in the aftermath of a corrective disclosure did not eviscerate an investor’s claim for damages. The Second Circuit’s decision was deemed “precedential” by the New York Law Journal, and provides critical guidance for assessing damages in a § 10(b) action.

Mr. Lieberman regularly consults with Pomerantz’s international institutional clients, including pension funds, regarding their rights under the U.S. securities laws. Mr. Lieberman is working with the Firm’s international clients to craft a response to the Supreme Court’s ruling in Morrison v. Nat’l Australia Bank, Ltd., which limited the ability of foreign investors to seek redress under the federal securities laws. Currently, Mr. Lieberman is representing several UK and EU pension funds and asset managers in individual actions against BP plc in the United States District Court for the Southern District of Texas.

Mr. Lieberman is a frequent lecturer regarding current corporate governance and securities litigation issues. In March 2017, he spoke at the ICGN conference in Washington D.C., regarding recent trends in foreign securities litigation. He also recently led a discussion regarding U.S. securities class actions in Paris, France.

Mr. Lieberman graduated from Fordham University School of Law in 2002. While in law school, he served as a staff member of the Fordham Urban Law Journal. Upon graduation, he began his career at a major New York law firm as a litigation associate, where he specialized in complex commercial litigation.

Mr. Lieberman is admitted to practice in the State of New York; the U.S. District Courts for the Southern and Eastern Districts of New York, the Southern District of Texas, the District of Colorado, the Eastern District of Michigan and Northern District of Illinois; the U.S. Courts of Appeals for the Second, Third, Fourth, Sixth, Ninth and Tenth Circuits; and the United States Supreme Court.
