The lawsuit, Beidel v. Sandgaard, et al., No. 1:26-cv-00714, was filed in the U.S. District Court for the District of Colorado. The action seeks to recover losses for all persons and entities who purchased or otherwise acquired Zynex securities during the Class Period: February 25, 2021, through December 15, 2025, inclusive.

"The Beidel complaint alleges a fundamental deception of the market regarding the source of Zynex's revenue." said Reed Kathrein, the Hagens Berman partner leading the firm's investigation of the claims in the pending suit. "The allegations suggest that Zynex's purported growth was not the result of legitimate demand, but was instead driven by a predatory 'oversupplying' scheme that targeted patients and defrauded payors."

Summary of Allegations: The "Oversupplying" Scheme

The filed complaint alleges that throughout the Class Period, defendants violated federal securities laws by failing to disclose.

• Systemic Overbilling: Zynex allegedly engaged in a scheme to ship patients excessive medical supplies—in some cases up to 128 electrode pairs per month—regardless of medical necessity, specifically to inflate billings to government and private payors. The lawsuit alleges that Zynex lacked effective internal controls to prevent the widespread manipulation of supply orders and billing data.
• 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.
• 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.
• 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.

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.
