The lawsuit alleges that Zynex lacked effective internal controls to prevent the widespread manipulation of supply orders and billing data.</li> <li>Tricare Suspension: In early 2025, Zynex's largest payor, Tricare, suspended all payments to the company. The complaint alleges management concealed the severity of this suspension until the company was forced to agree to forfeit over $85 million to resolve the fraud allegations.</li> <li>Criminal Indictments: On January 21, 2026, former CEO Thomas Sandgaard and former COO Anna Lucsok were indicted for health care and securities fraud, leading to their immediate removal from the company.</li> <li>Total Value Destruction: Following the exposure of these practices and the massive forfeiture, Zynex filed for Chapter 11 bankruptcy and was delisted from the Nasdaq, resulting in a near-total loss for common equity holders.</li> </ul> Critical Deadline: April 21, 2026 If you purchased Zynex common stock during the Class Period (February 25, 2021 – December 15, 2025), you have until April 21, 2026, to ask the Court to appoint you as Lead Plaintiff. <ul type="disc"> <li>SUBMIT YOUR ZYNEX LOSSES NOW</li> <li>CONTACT: REED KATHREIN AT 844-916-0895 OR EMAIL [email protected]</li> </ul> If you'd like more information and answers to frequently asked questions about the Zynex case and the firm's investigation, read more » Whistleblowers: Persons with non-public information regarding Zynex should consider their options to help in the investigation or take advantage of the SEC Whistleblower program.
