Zimmerman Reed Class Action Lawsuits: Data Breach, Pharma, and Securities

Zimmerman Reed LLP is a Minneapolis plaintiffs’ firm that has served as lead or co-lead counsel in some of the largest class action lawsuits in the United States, recovering billions of dollars in cases involving data breaches, defective medical devices, pharmaceutical injuries, securities fraud, antitrust violations, and NFL concussion injuries.¹ Founded in 1983, the firm concentrates on class actions and complex litigation and continues to represent consumers, investors, workers, and public clients in active cases across the country.²

About the Firm

Zimmerman Reed’s headquarters sits at the IDS Center on South 8th Street in Minneapolis, with additional offices in Phoenix and Los Angeles.³⁴ Its managing partners are June Pineda Hoidal, Caleb L. H. Marker, and J. Gordon Rudd, Jr. The firm’s practice spans antitrust, consumer protection, employment and overtime claims, financial fraud, mass torts, medical devices and pharmaceuticals, privacy and data breach, public client work, sports law, whistleblower actions, and wildfire litigation.⁵

Data Breach and Privacy Class Actions

Data breach work has become one of the firm’s defining areas. Zimmerman Reed served as lead counsel for financial institutions in the Target data breach litigation in the U.S. District Court for the District of Minnesota.⁶ The breach compromised 40 million credit and debit cards and the personal information of 110 million consumers. The financial institution track settled for $59.4 million in May 2016 and was one of the first certified classes in a data breach action.⁷

The firm was later appointed co-lead counsel for financial institutions in the Sonic data breach litigation in the Northern District of Ohio, MDL No. 2807. Judge James S. Gwin granted final approval to a $5.73 million settlement in October 2022.⁸ Zimmerman Reed also served on the Plaintiffs’ Steering Committee in the Home Depot data breach litigation, representing banks and credit unions after a breach exposed payment card data for 40 million customers.⁷

In the T-Mobile data breach litigation, attorney Rachel Tack served on the Plaintiffs’ Executive Committee. The case arose from a 2021 cyberattack affecting approximately 76 million U.S. consumers.⁹ T-Mobile agreed to a $350 million settlement fund for consumer losses plus $150 million for data security improvements. Judge Brian C. Wimes in the Western District of Missouri granted final approval in June 2023, and settlement payments have been distributed.¹⁰

Active Privacy and Pixel Tracking Cases

The firm represents plaintiffs in a proposed class action against Costco alleging the retailer improperly disclosed customers’ personal health information by embedding Meta Pixel and similar Facebook tracking tools on its pharmacy website. The case is before Judge John H. Chun in the U.S. District Court for the Western District of Washington, where Costco has sought sanctions against the plaintiffs over disputed “missing devices.”¹¹

In June 2026, a federal judge in the Eastern District of Michigan granted preliminary approval to a $17.5 million settlement resolving data breach claims against 700Credit LLC, a credit-reporting and identity-verification company that serves auto dealerships. The breach, discovered around October 2025, exposed names, addresses, dates of birth, and Social Security numbers of approximately 5.8 million people. A final approval hearing is scheduled for December 2026.¹²

Pharmaceutical and Medical Device Class Actions

Zimmerman Reed participated in Roundup cancer litigation that yielded an $11 billion recovery for patients diagnosed with non-Hodgkin’s lymphoma, and in Stryker hip replacement litigation that directed over $2 billion to patients injured by recalled components. In opioid litigation brought on behalf of state attorneys general, including Indiana and Vermont, the firm helped secure a $26 billion settlement with major distributors and Johnson & Johnson.¹

Other pharmaceutical results include a $1.15 billion settlement in the Baycol cholesterol drug litigation for 2,500 clients and a $27 million settlement in Zicam cases involving loss of sense of smell. In medical devices, the firm recovered $95.6 million for 2,682 patients in Medtronic defibrillator litigation and $240 million for 8,500 patients in a separate Guidant defibrillator settlement. Dicamba crop-damage litigation, in which Bayer agreed to pay up to $400 million for damage to farms between 2015 and 2020, is also among the firm’s notable results.¹

NFL Concussion and Sports Litigation

Zimmerman Reed represented hundreds of former NFL players in concussion litigation against the league. The uncapped settlement that resulted has paid more than $1 billion to over 4,500 retired players.¹ The firm separately represented retired players in a publicity rights dispute that produced a settlement creating a licensing agency for the group rights of former players.¹³

Securities Fraud and Antitrust Class Actions

The firm has recovered substantial sums in securities fraud class actions. Results include a $50 million settlement with St. Jude Medical, Inc. for alleged violations of the Securities Exchange Act of 1934 and a $43 million settlement in Medtronic securities fraud litigation. Other financial recoveries include $125 million in the Morgan Keegan lawsuit, $75 million in Merrill Lynch ERISA litigation, and $62.5 million in Wells Fargo securities lending litigation.¹

On the antitrust side, Zimmerman Reed secured a $225 million settlement in Vitamins Antitrust Litigation and a $20 million settlement in Metoprolol Succinate Antitrust litigation. In an LCD price-fixing case, the firm secured a U.S. Supreme Court ruling in favor of the State of Mississippi.¹

Consumer Protection, Employment, and Whistleblower Cases

Zimmerman Reed secured $26.5 million in combined settlements in Telephone Consumer Protection Act cases and recovered more than $12 million against National Computer Systems over incorrectly scored standardized tests that affected nearly 8,000 students. In Pilot Flying J litigation, the firm reached a settlement that guaranteed trucking companies compensation for unpaid fuel rebates and discounts, plus 6% annual interest.¹⁴

Employment recoveries include $7.25 million in combined settlements for unpaid overtime claims and $1.5 million against Farmers Insurance regarding overtime misclassification. The firm currently represents rideshare and gig economy drivers in individual arbitrations, alleging misclassification as independent contractors and improper deductions for expenses such as insurance, gas, and vehicle maintenance.¹

In April 2024, the firm announced a $7 million False Claims Act settlement with ReNew Health Group LLC, its consulting affiliate, and two executives, who were accused of submitting fraudulent Medicare and California Medicaid claims beginning in March 2020.¹⁵ Whistleblowers alleged the nursing homes exploited a temporary CMS waiver that had lifted the usual three-day hospital stay requirement for skilled nursing facility reimbursement, submitting claims for residents who did not have COVID-19 or any acute illness but had “merely been near other people who had COVID-19.” Roughly $6.8 million went to the United States and $242,273 to California, with the whistleblowers receiving approximately $1.2 million. The settlement resolved the allegations without a determination of liability.¹⁶

MDL Leadership Appointments

Federal courts have repeatedly appointed Zimmerman Reed attorneys to leadership positions in multidistrict litigation, which carry responsibility for coordinating discovery, managing expenses, and negotiating settlements for large plaintiff classes. Managing partner Gordon Rudd served on the Plaintiffs’ Executive Committee in the Abilify products liability MDL in the Northern District of Florida.¹⁷ Partner Chris Ridout was appointed to the Plaintiffs’ Executive Committee in the Apple iPhone battery throttling MDL in May 2018.¹⁸ Partner Michael Laird has served on leadership committees in the ParkMobile consumer data breach litigation and the Elanco flea and tick pet collar litigation, among others.¹⁹

Current Investigations

Through its ZR Claims intake site, the firm lists several active investigations. These include a consumer protection investigation into bikes purchased since February 2025, a probe into whether Hims & Hers engaged in deceptive advertising regarding compounded weight loss injections, a review of potentially excessive healthcare insurance pricing, and gig economy worker rights claims involving Amazon Flex drivers. In the personal injury space, the firm continues to represent individuals who developed Parkinson’s disease after exposure to the pesticide Paraquat.²⁰
