Zynex shares surge 32.31% after-hours as company enters Chapter 11 restructuring with lender-backed financing.

Zynex, Inc. (NASDAQ: ZYXI) surged 32.31% in after-hours trading following its announcement of a voluntary Chapter 11 financial restructuring supported by new financing from lenders. The company emphasized that the restructuring, which allows operations to continue uninterrupted, reflects lender confidence in its business and strategic improvements, positioning Zynex for long-term stability. While earlier news had reported a 55.2% stock plunge in December 2025 after the Chapter 11 filing, the recent after-hours rally suggests renewed investor optimism tied to the restructuring’s execution and management’s assurances of operational continuity. The key catalyst appears to be the restructuring’s framing as a path to resolve financial challenges, contrasting with prior bearish sentiment.
