Firm overview

History: Pomerantz is the oldest law firm in the world dedicated to championing investor rights. Founded in 1936 by Abraham Pomerantz, the Firm’s work during the Great Depression to hold corporations accountable helped secure the rights of investors to bring class actions and derivative suits. Today the Firm’s global clients include more than 100 of the most influential public pension funds, asset managers, and private institutions. Honoring its founder’s legacy, the Firm continues to fight for defrauded shareholders while expanding the rights of global investors and championing transparent markets and good corporate governance.


Securities Litigation:
Over the past eight decades the Firm has recovered billions of dollars for defrauded investors, with many settlements achieving new records. Notable matters include:

  • A $3 billion settlement in litigation against Brazil’s state-run oil company Petrobras, involving an alleged decades-long corruption scheme that ensnared multiple former Brazilian presidents, among many others. The recovery stands as the fifth-largest securities class action settlement ever achieved in the United States (In re Petrobras Securities Litigation).
  • A $225 million recovery for the Class in a suit against Comverse Technology, Inc., the second-largest recovery involving the backdating of stock options (In re Comverse Technology, Inc. Securities Litigation).
  • A $110 million settlement with Fiat Chrysler Automobiles N.V. that opened new avenues for discovery in securities litigation (Pirnik v. Fiat Chrysler Automobiles N.V., et al.).
  • A $74 million settlement for investors in Arconic, whose insulation panels were implicated in the June 2017 fire at Grenfell Tower in London (Howard v. Arconic et al.).


A Tradition of Innovation:
Pomerantz is a recognized leader in developing novel legal theories to address the evolving juridical, social, and corporate landscape. For example, the U.S. Supreme Court’s ruling in Morrison v. National Australia Bank, Ltd (2010) barred investors in foreign securities from using U.S. courts to seek recovery. In the years since, Pomerantz has worked to win back these rights on behalf of investors. In a series of individual cases arising out of the 2010 BP Gulf of Mexico oil spill, Pomerantz convinced the court to allow, for the very first time post-Morrison, both U.S. and foreign investors seeking recovery for losses in a foreign company’s foreign-traded securities to do so in a U.S. court. In a securities class action against the global pharmaceutical company Perrigo Co., the Firm’s ground-breaking legal arguments led the U.S. court, for the first time since the Morrison decision, to certify a foreign purchaser class. Both decisions have significant precedential value, expanding the options available for domestic and foreign investors seeking recovery in cases of securities fraud.


Portfolio Monitoring:
PomTrack®, the Firm’s proprietary portfolio monitoring system, tracks and evaluates suspicious market activity, as well as securities and antitrust class actions and settlements, covering both domestic and international events. This system empowers investment plan fiduciaries to fulfill their duty to preserve investments by quickly identifying fund losses that may have been caused by financial misconduct. Comprising attorneys, forensic economists, damages analysts, paralegals, and support staff, the PomTrack® team monitors assets valued at over $9 trillion, making it one of the largest systems of its kind in the U.S. 


ESG:
Pomerantz partners are pioneering securities litigation as a means to address 21st century ESG concerns. The Firm achieved a settlement with Deutsche Bank AG that recoups nearly 50% of estimated damages for investors in a case alleging that the bank failed to adhere to its own due diligence policies for certain high-worth clients, including convicted sex offender Jeffrey Epstein. Pomerantz also recently won class certification in its case against Wynn Resorts Ltd., which alleges that former CEO Steve Wynn engaged in egregious sexual misconduct against the company’s female employees, while the company and its directors simultaneously covered up his behavior, assuring investors of the company’s commitment to high ethical standards. 


Corporate Governance:
In addition to addressing corporate governance via securities litigation, the Firm’s Corporate Governance Practice Group has achieved significant corporate governance reform at numerous major corporations through shareholder derivative lawsuits. Areas of interest include workers’ health and safety, environmental compliance, pay and gender equity, excess executive compensation, and addressing corporate transactions that result in an unfair price for shareholders. 


Education:
Pomerantz partners frequently speak on corporate governance at conferences around the world, and the Firm regularly hosts Corporate Governance Roundtables for institutional investors. The Firm also publishes The Pomerantz Monitor, a bi-monthly journal of attorney-authored articles on securities litigation, corporate governance, and related regulatory and government policies.

Dispute Resolution

A plaintiff shop with offices in New York, Chicago and Los Angeles, covering both coasts as well as the heartland, Pomerantz is known for its prodigious capacity for cases and its tenacity to keep pursuing them. Historically known for its concentration in the securities class actions area, the firm has been, according to peers, “pursuing cases that go beyond your typical plain-vanilla work.” One contemporary specifies, “Not to denigrate firms that bring the standard 10b-5 and stock-drop cases of merit, but I feel like Pomerantz is chasing some work with more meaningful angles right now.” Another peer testifies, “I’ve seen a fair bit of them over the past year, and I would say as far as plaintiff shops go, they are in the ‘A’ tier.”
     In one example of a case with extraordinary ramifications, Emma Gilmore, along with Jeremy Lieberman, secured final court approval in August 2023 of a $74 million settlement on behalf of the investor class in this securities class action that arose from the deadliest UK fire in more than a century, the Grenfell Tower fire in London, which killed 72 people in June 2017. Plaintiffs alleged that the stock price of the tower’s developer, Arconic, was artificially inflated by misstatements by the company regarding the safety of the insulation panels that were later implicated in the fire. In another, the same duo Same duo secured final approval of a $26.25 million settlement for defrauded investors in this securities class action brought against Deutsche Bank for its misstatements about the efficiency of its anti-money laundering and Know-Your-Customer controls. The complaint alleged that, contrary to its public statements about the robustness of its controls, Deutsche Bank failed to flag transactions made on behalf of its high-risk, high-net-worth customers, including convicted sex offender Jeffrey Epstein. In yet another, Murielle Steven Walsh is lead counsel in a securities fraud class action against Wynn Resorts, which stems from the alleged decades-long pattern of sexual abuse and harassment perpetrated by the company’s founder and former CEO, Steve Wynn. The complaint alleges that Wynn and its executives misled investors when they denied allegations by Wynn’s ex-wife that he had engaged in serious misconduct against a company employee. Years later, when the Wall Street Journal published a detailed account of numerous former employees’ complaints of sexual abuse by Wynn, the company’s stock price plummeted, and yet the company continued to deny that any wrongdoing had occurred and that the allegations had been fabricated by Wynn’s ex-wife.
