Pomerantz LLP is the oldest securities litigation firm in the United States and one of the most highly respected. The firm was founded in 1936 by legal pioneer and “dean” of the plaintiffs’ securities bar, Abraham L. Pomerantz, who helped secure the rights of investors to bring class and derivative actions.

Pomerantz protects and vindicates shareholder rights through its securities litigation services and proprietary PomTrackÒ portfolio monitoring program. The firm’s global clients include more than 100 of the largest and most influential pension funds, asset managers and private institutions, with combined assets of over $5 trillion. Pomerantz’s practice also includes corporate governance, antitrust and consumer litigation.

Over the years, Pomerantz has accomplished important wins for plaintiffs against Fortune 500 companies whose counsel are some of the most powerful global defense firms. In January 2018, Pomerantz secured a $3 billion settlement for defrauded Petrobras investors – the largest settlement ever achieved against a foreign company and the largest settlement in the U.S. in over a decade.

The firm is regularly appointed sole lead counsel in complex securities class actions, representing entire classes of defrauded shareholders.

Pomerantz and its attorneys consistently earn the trust of its clients, the respect of both adversaries and peers and praise from the courts.

Jeremy A. Lieberman, Pomerantz’s Managing Partner who led Pomerantz’s litigation against Brazilian oil giant, Petrobras, was named a 2018 Titan of the Plaintiffs’ Bar by Law360. He was honored as a Super Lawyers® “Top-Rated Securities Litigation Attorney” in 2016, 2017 and 2018. The Legal 500, in naming Pomerantz a Leading Firm for 2016 and 2017, wrote that “Jeremy Lieberman is super impressive – a formidable adversary for any defense firm.”

In 2019 Jennifer Pafiti, Partner and Head of Client Services, was named to Benchmark Litigation’s 40 & Under Hot List of the best young attorneys in the United States; was honored by Super Lawyers® as a Southern California Rising Star; and was named by The American Registry as one of Southern California’s Top Young Lawyers. In 2018 she was named to Benchmark Litigation’s 2018 40 & Under Hot List and recognized as a Lawyer of Distinction. In 2017 she was named a Super Lawyers® Rising Star and one of the Top Women Attorneys in Southern California. In 2016, the Daily Journal selected her for its Top 40 Under 40 list of the best young attorneys in California. 

In early 2018, Pomerantz, as sole lead counsel, achieved a landmark $3 billion settlement for investors in the securities class action against Petróleo Brasileiro S.A. – Petrobras. The allegations arose from a decades-long, multi-billion-dollar corruption scheme—a scandal that ensnared not only Petrobras' former executives, but also Brazilian politicians, including every former and current living Brazilian president and at least one third of the Brazilian Congress. This historic settlement represents:

  • the largest securities class action settlement in a decade;
  • the largest settlement ever in a securities class action involving a foreign issuer;
  • the fifth-largest class action settlement ever achieved in the United States;
  • the largest class action settlement ever achieved by a foreign lead plaintiff; and
  • the largest class action settlement ever not involving a restatement of financial reports.

Throughout the Petrobras litigation, Pomerantz achieved important precedents at the Second Circuit Court of Appeals that will form the bedrock of securities class action jurisprudence and help protect investors for decades to come.

In August 2019, Pomerantz achieved final approval of a $110 million settlement in a securities class action against Fiat Chrysler N.V., one of the world’s largest car manufacturers, for allegations that the company misled investors about its compliance with regulations for safety recalls and emissions. In late 2018, the firm achieved an $80 million settlement in the class action litigation against Yahoo! Inc., arising from one of the largest data breaches in U.S. history and represents the first significant settlement of a securities fraud class action filed in response to a data breach. Also in 2018, Pomerantz secured a $31 million partial settlement in In re Libor Based Financial Instruments Antitrust Litigation, a closely-watched case concerning the London Interbank Offered Rate rigging scandal.

Partner and Head of Client Services, Jennifer Pafiti, dually qualified to practice in the U.S. and the United Kingdom, regularly travels the globe to advise clients on how best to evaluate losses to their investment portfolios attributable to financial fraud or other misconduct and how best to maximize their potential recoveries. The firm’s Paris office is headed by French lawyer, Nicolas Tatin, Pomerantz’s Director-Business Development Consultant for France, Benelux, Monaco and Switzerland. In addition to the firm’s in-house team in the U.S. and Paris, Pomerantz utilizes an extensive network of prominent law firms across the globe. Pomerantz attorneys are collectively fluent in English, Arabic, Mandarin-Chinese, Farsi, French, Hebrew, Italian, Portuguese, Romanian, Russian, Spanish and Taiwanese.

Judge Jed S. Rakoff of the United States District Court for the Southern District of New York stated at the February 2018 hearing for preliminary approval of the $3 billion settlement achieved by Pomerantz in In re Petrobras Securities Litigation:

     ...the lawyers in this case [are] some of the best lawyers in the United States, if not in the world.

In approving the Petrobras settlement in June 2018, Judge Rakoff wrote:

     [T]he Court finds that Class Counsel's performance was in many respects exceptional, with the result that, as

     noted, the class is poised to enjoy a substantially larger per share recovery [65%] than the recovery enjoyed by

     numerous large and sophisticated plaintiffs who separately settled their claims.

In approving the settlement in Thorpe v. Walter Investment Management Corp. in October 2016, Judge Ursula Ungaro wrote:

     Class Counsel has developed a reputation for zealous advocacy in securities class actions. ... The settlement

     amount of $24 million is an outstanding result.
