Michael Grunfeld joined Pomerantz in July 2017 as Of Counsel and was elevated to Partner in 2019. He has extensive experience in securities, complex commercial, and white-collar matters in federal and state courts around the country. In particular, Michael has represented issuers, underwriters, and individuals in securities class actions dealing with a wide variety of industries. He has also represented financial institutions and individuals in cases related to RMBS, foreign exchange practices, insider trading, and other financial and consumer matters.  Michael was honored in 2019 as a Super Lawyer® in the New York Metro area, and in 2018 as a Super Lawyers® Rising Star.

Michael played an integral role in Pomerantz’s ground-breaking litigation against Yahoo! Inc., In re Yahoo! Inc. Securities Litigation, No. 5:17-cv-00373 (N.D. Cal.), for Yahoo’s alleged failure to disclose the largest data breaches in history at the time.  This matter resulted in an $80 million settlement for the Class. 

Michael also played a key role in shepherding the historic $3 billion settlement in In re Petrobras Securities Litigation, No. 1:14-cv-09662 (S.D.N.Y.), to agreement by the parties and court approval. He was the point person who assisted Managing Partner Jeremy Lieberman in drafting the settlement papers, negotiating the settlement details with defendants, and strategizing how to protect the settlement from objections.

In addition, Michael plays a leading role in the Firm’s representation of the Colorado Public Employees’ Retirement Association (“Colorado PERA”) as a proposed intervenor in The Doris Behr 2012 Irrevocable Trust v. Johnson & Johnson, No. 3:19-cv-08828 (D.N.J.). This unique case pits a small shareholder seeking to propose a bylaw amendment that would mandate arbitration – and eliminate class actions – for securities claims against a large corporation that is defending the right of its shareholders to sue to the company.  Pomerantz, via this litigation, seeks to protect the rights of investors to continue to bring and participate in securities class actions.

Michael leads the Firm’s litigation in Lerman, et al. v. Apple Inc., No. 1:15-cv-7381-SJ-LB (E.D.N.Y.), which is a putative consumer class action against Apple related to the allegation that the iOS 9 operating system harmed the performance of iPhone 4s devices. h

He is also leading several other securities class actions at various stages in the litigation process, including matters where the amended complaints or motion to dismiss briefing are pending.

Michael is the co-author of a chapter on damages in securities class actions in the LexisNexis treatise, Litigating Securities Class Actions.

Michael served as a clerk for Judge Ronald Gilman of the Sixth Circuit Court of Appeals and as a foreign law clerk for Justice Asher Grunis of the Israeli Supreme Court. Before joining Pomerantz, he was a litigation associate at Shearman & Sterling LLP and Paul, Weiss, Rifkind, Wharton & Garrison LLP. Michael graduated from Columbia Law School in 2008, where he was a Harlan Fiske Stone Scholar and Submissions Editor of the Columbia Business Law Review. He graduated from Harvard University with an A.B. in Government, magna cum laude, in 2004.

Michael is admitted to practice in the State of New York, the Second, Fourth, Sixth, and Tenth Circuit Courts of Appeals, and the United States District Courts for the Southern and Eastern Districts of New York and the District of Colorado.
