Jeremy A. Lieberman

Jeremy A. Lieberman joined the Firm in 2004 and has served as Pomerantz’s Managing Partner since 2016. He oversees all the Firm’s cases and initiatives across its six offices. In two decades of representing plaintiffs in securities fraud cases, Jeremy has recovered billions of dollars for damaged investors, secured seminal court decisions expanding global investors’ rights, and helped bring about meaningful corporate governance reform. Under his leadership, Pomerantz has expanded its global presence by opening offices in London and Paris.

Jeremy has earned numerous accolades, emphasizing his outstanding skills and commitment to the field. He’s been recognized by Lawdragon as one of the Leading 500 Plaintiff Financial Lawyers in the U.S. from 2019 to 2024, and again in 2026, and by Super Lawyers® as one of the Top 100 Lawyers in the New York Metro area every year since 2021. In 2020, he received the Distinguished Leader award from the New York Law Journal. He was honored as the 2019 Plaintiff Attorney of the Year by Benchmark Litigation and named a Titan of the Plaintiffs Bar by Law360 in 2018.

Jeremy has traveled the globe for decades, advising institutional investors and listening to their needs. When the Supreme Court’s 2010 decision in Morrison v. Nat’l Australia Bank barred purchasers of securities on non-U.S. exchanges from pursuing claims in U.S. courts under the federal securities laws, Jeremy developed novel legal theories in response. He systematically deconstructed the legal barriers raised by Morrison through a series of novel arguments that set groundbreaking precedents in favor of global shareholders in securities litigations led by Pomerantz against BP plc, Perrigo Co. plc, Teva Pharmaceutical Industries Ltd. and Ormat Technologies, Inc.

Beyond advisory roles, Jeremy leads Pomerantz’s educational initiatives. The firm organizes conferences and talks globally, and its Corporate Governance Roundtables offer institutional investors and governance experts worldwide a platform to discuss issues impacting the value of their funds.

Jeremy is a frequent lecturer on corporate governance and securities litigation issues worldwide, sharing his insights and fostering understanding across diverse legal systems.

Jeremy led the litigation of In re Petrobras Securities Litigation, in which Pomerantz, as sole Lead Counsel, achieved a stunning $3 billion settlement for defrauded investors, the largest securities class action settlement in a decade, and the fifth largest in US history.

Beyond the exceptional financial recovery, Jeremy 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 form the bedrock of securities fraud litigation for decades to come. Jeremy’s role in the Petrobras litigation was covered by leading news media around the globe, including the New York Times, the Financial Times, the Wall Street Journal, Forbes, and Piauí, a prominent Brazilian journal.

Some of Jeremy’s other notable cases include:

• In re Petrobras Securities Litigation: Jeremy led the Firm’s securities class action against Brazil’s state-run oil company, Petrobras, achieving a record-setting $3 billion recovery in 2018. The litigation arose from the largest corruption scandal in Brazil’s history, a bribery and money laundering scheme that ensnared multiple Brazilian presidents and one third of Brazil’s congress. The case spanned three years of hard-fought litigation, involving 51 live fact witness depositions and review of over 2 million documents in 5 languages. During the litigation, Jeremy also secured important rulings in the Second Circuit Court of Appeals,
• Roofer’s Pension Fund v. Papa, et al.: In 2024, Jeremy secured a $97 million settlement in a securities class action against the pharmaceutical company Perrigo relating to allegedly misleading statements made by the company in order to fend off a hostile takeover bid by fellow drug manufacturer Mylan. In a groundbreaking ruling, the court agreed to certify parallel classes of investors who had purchased stock on the New York Stock Exchange and the Tel Aviv Stock Exchange. This marked the first time a U.S. court had certified a foreign purchaser class since the U.S. Supreme Court’s ruling in Morrison v. National Australia Bank Ltd., which barred foreign investors from pursuing recovery relating to purchases of foreign securities on foreign exchanges in U.S. courts.
• In re Teva Securities Litigation: Jeremy led the Firm’s opt-out litigation against Teva Pharmaceuticals on behalf of 22 Israeli institutional investors, resulting in a favorable confidential settlement in January 2024. The case concerned Teva’s participation in an alleged price-fixing scheme, as well as the company’s role in the U.S. opioid crisis. During the litigation, Pomerantz convinced the court to apply supplemental jurisdiction over claims under Israeli law involving Teva shares that were dual-listed on the New York Stock Exchange and the Tel Aviv Stock Exchange. This is an important victory in the wake of the Morrison ruling, providing a road map for investors to pursue recovery in claims involving dual-listed shares.
• Pirnik v. Fiat Chrysler Automobiles N.V.: Jeremy and Partner Michael J. Wernke led Pomerantz’s securities class action against Fiat Chrysler relating to the company’s use of “defeat device” technology to bypass NOx emissions regulations in the U.S. and Europe.

In addition to securing a $110 million settlement in 2019 representing as much as 20% of estimated recoverable damages, the case established the important precedent that Touhy regulations do not shield former federal employees from testifying in court. This has expanded the toolbox available for plaintiffs, allowing attorneys to depose former federal employees in highly regulated industries.

• Strougo v. Barclays PLC: In 2019, Jeremy achieved a $27 million settlement for the Class in this securities class action he led with Partner Tamar A. Weinrib, in which Pomerantz was Lead Counsel. Plaintiffs alleged that 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 turned on the duty of integrity owed by Barclays to its clients. In November 2017, Jeremy 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.
• Yahoo! Inc.: Jeremy and Partner Emma Gilmore led this securities class action against Yahoo! Inc., in which Pomerantz, as Lead Counsel, achieved an $80 million settlement for the Class in 2018. The case involved the biggest data breaches in U.S. history, in which over 3 billion Yahoo accounts were compromised. This was the first significant settlement to date of a securities fraud class action filed in response to a data breach.
• Erickson v. Corinthian Colleges, Inc.: In 2018 Jeremy achieved a $3 million settlement for the Class in the firm’s securities class action against Corinthian Colleges, one of the largest for-profit college systems in the country, for alleged misrepresentations about its job placement rates, compliance with applicable regulations, and enrollment statistics. Pomerantz prevailed in the motion to dismiss the proceedings, a particularly noteworthy victory because Chief Judge George King of the Central District of California had dismissed two prior lawsuits against Corinthian with similar allegations.
• In re Libor Based Financial Instruments Antitrust Litigation: Jeremy, with Partner Michael J. Wernke, secured a $31 million partial settlement with three defendants in this multi-district litigation that concerned the London Interbank Offered Rate (LIBOR) rigging scandal.
• In re China North East Petroleum Corp. Securities Litigation: Jeremy 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.
• In re Comverse Technology, Inc. Securities Litigation, Jeremy had an integral role in this securities class action in which Pomerantz achieved a historic $225 million settlement on behalf of the Class — the second-largest options backdating settlement to date at the time.
• Ferris, et al. v. Wynn Resorts Limited, et al.: Jeremy helped lead this securities class action in which Pomerantz achieved class certification on behalf of investors. The case, arising from decades-long sexual misconduct by Steve Wynn and the company’s cover-up, shows that securities laws apply with full force to issues of executive misconduct and corporate accountability.
