On August 18, 2026, U.S. District Judge Brian R. Martinotti of the District of New Jersey denied Coinbase’s motion to dismiss a shareholder class action against the world’s largest crypto exchange. This was Coinbase’s third dismissal motion in this long-running securities class action led by Lead Plaintiff Sjunde AP-Fonden (AP7), one of Sweden’s largest pension funds. The motion followed the filing of an amended complaint in October 2025.

Plaintiffs allege that Coinbase, its CEO Brian Armstrong, and other senior executives failed to disclose the true regulatory risks facing the nascent crypto platform, including the likelihood that the SEC would pursue an enforcement action against Coinbase for failing to register the digital assets it lists as securities with the Commission. In June 2023, when the SEC filed an enforcement action against Coinbase, the company’s stock tumbled, causing massive investor losses.

In denying Coinbase’s motion, Judge Martinotti underscored the plaintiffs’ allegations of insider trading. The Court found that the amended complaint submits facts that “support the assertion defendants had motive to engage in wrongful conduct at the time of the allegedly misleading statements – the reaping of billions of dollars in financial benefits by cashing out existing shares at inflated values following Coinbase’s public listing before the public could learn about the risks associated with a potential bankruptcy and/or an [SEC] enforcement action.” The case, pending since 2023, will now proceed to discovery.

The KTMC team representing plaintiffs includes Matthew Mustokoff, Stacey Kaplan, Margaret Mazzeo, and Joshua Materese.

On August 5, 2026, Judge Noël Wise of the Northern District of California issued a significant ruling for investors in In re SVB Financial Group Securities Litigation, the class action arising from the March 2023 collapse of Silicon Valley Bank.

The Court granted Lead Plaintiffs Sjunde AP-Fonden (AP7) and Norges Bank’s motion to amend the complaint to add a Section 10(b) securities fraud claim against KPMG LLP, SVB’s longtime outside auditor and denied KPMG’s motion to dismiss that claim in full. Those claims are based on approximately 300 new allegations drawn from KPMG’s own workpapers and internal files produced in discovery. In denying KPMG’s motion, the Court held that Plaintiffs adequately alleged that KPMG acted with scienter. Among other facts, the Court pointed to escalating red flags KPMG confronted regarding SVB’s ability to hold its massive held-to-maturity securities portfolio to maturity—a portfolio that grew 500% in a single year and whose unrealized losses ultimately approached 95% of SVB’s shareholders’ equity.

KPMG now faces both Securities Act and Exchange Act fraud claims as the case proceeds toward class certification and trial.

KTMC serves as co-lead counsel with a team that includes Sharan Nirmul, Rick Russo, Jamie McCall, Sarah Damiani, Nate Simon, Lyndsey Campbell and Mariama Barry. Partner Sharan Nirmul argued the motions on July 29, 2026.

KTMC Prevails in Federal Appeal, Successfully Defending Its $812 Million Jury Verdict for Fannie and Freddie Shareholders

On July 24, 2026, the U.S. Court of Appeals for the D.C. Circuit issued a ruling upholding the $812 million trial verdict and judgment for plaintiff shareholders of the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). This major victory is the latest in our long-running litigation stemming from the August 2012 “Net Worth Sweep,” in which the Federal Housing Finance Agency (“FHFA”) agreed to permit the U.S. Treasury to “sweep” 100% of Fannie and Freddie’s profits in perpetuity, thereby depriving Fannie Mae and Freddie Mac shareholders of any opportunity to benefit from those future profits in the form of dividends or through building net worth at the companies.

KTMC, along with co-counsel, achieved the unanimous jury verdict at the center of this appeal in August 2023, after a three-week trial in the U.S. District Court for the District of Columbia. The jury found that FHFA breached the implied covenant of good faith and fair dealing in the Fannie and Freddie shareholder contracts because the Net Worth Sweep was an “arbitrary and unreasonable” violation of shareholders’ reasonable expectations. Of the many lawsuits challenging the “Net Worth Sweep,” our litigation brought the only successful cause of action. We have litigated Fannie Mae and Freddie Mac stockholders’ implied covenant claim through multiple rounds of pleadings, prior appeals, and a prior three-week trial that ended in a mistrial in 2022.

Telemedicine Company and Physician to Pay Over $3.3 Million To Settle Whistleblower Lawsuit Alleging Fraudulent Billing

The Department of Justice announced that Circle Medical Technologies, Inc., a nationwide telemedicine company, its affiliated physician group, Circle Medical Care of California, and their Chief Medical Officer and medical director, Dr. Nicole Tsang, D.O., (collectively, “Circle Defendants”) have agreed to pay the United States and State of California $3,325,000 to settle a qui tam lawsuit filed in the U.S. District Court for the Northern District of California.

Asher Alavi and David Bocian of KTMC represented the whistleblower, Jason Vellen, and filed the qui tam lawsuit under seal in 2024 pursuant to the whistleblower provisions of the federal False Claims Act and California Insurance Frauds Prevention Act. In June 2026, the United States and State of California intervened in the lawsuit for purposes of settlement.

The settlement, one of the first of its kind involving a telemedicine company, resolves allegations that the Circle Defendants defrauded federally funded healthcare programs and private insurance plans in California by billing numerous telemedicine visits provided by its roughly 350 providers to patients throughout the country under the name and NPI of a physician who neither provided nor supervised the visits. In fact, the telemedicine visits, which were primarily related to the prescription of ADHD medication, were overwhelmingly performed by contracted physician-assistants and nurse practitioners, who were not properly supervised by the rendering provider listed on the claims.
