Appointment of Bret W. Wise as Director

On October 7, 2025, the Board of Directors (the “Board of Directors”) of Zynex, Inc.

Each such annual retainer will be pro-rated in the event that Mr. Wise’s service as a director terminates before the expiration of any three-month period for which such annual retainer was paid. Mr. Wise is also entitled to receive (i) an initial award of 20,000 shares of restricted stock and (ii) an annual award of 10,000 shares of restricted stock upon being re-elected to the Board of Directors, which awards vest quarterly in equal installments over three years beginning one quarter after the grant date, subject to Mr. Wise’s continued service on the Board of Directors through each such vesting date.
