Jeremy A. Lieberman serves as Co-Managing Partner of Pomerantz, and Managing Partner of the firm’s New York Office. Mr. Lieberman became associated with the Firm in August 2004, and became a partner in January 2010. Mr. Lieberman was recognized as a Super Lawyer in the New York Metro region for the year 2016.

Mr. Lieberman serves as lead counsel in In re Petrobras Sec. Litig., one of the most 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. Mr. Lieberman secured a significant victory for investors in this case at the Second Circuit Court of Appeals, when the Court rejected the heightened ascertainability requirement for obtaining class certification that had been imposed by other Circuit courts such as the Third and Sixth Circuit Courts of Appeals. 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’s skill in prosecuting securities class actions has been noted in a number of legal publications. Recently, the well-regarded Legal 500 commented:

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

Mr. Lieberman serves as lead counsel in a putative securities class action that alleges Barclays PLC misled investors about the manipulation of the banking giant’s use of so-called “dark pool” trading systems in order to provide a trading advantage to high-frequency traders over its institutional investor clients. In addition, Mr. Lieberman 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. He also serves as Interim Class Counsel on behalf of a class of lenders and financial institutions litigating claims arising out of the London Interbank Offered Rate (“LIBOR”) rate rigging scandal.

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. He 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.
