On June 13, 2022, Zynex, Inc. (the “Company”) notified Plante & Moran, PLLC (“Plante Moran”) as the Company’s independent registered public accounting firm of its dismissal (the “Effective Date”). The dismissal of Plante Moran was approved by the Audit Committee (the “Audit Committee”) of the Board of Directors (the “Board”) of the Company and the full Board on June 13, 2022. The reports of Plante Moran on the Company’s consolidated financial statements as of and for the years ended December 31, 2021 and 2020 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the Company’s fiscal years ended December 31, 2021 and 2020 and through the date of this Current Report on Form 8-K, there was no disagreement between the Company and Plante Moran on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to Plante Moran’s satisfaction, would have caused Plante Moran to make reference to the subject matter of the disagreement in connection with its reports for such fiscal years; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided Plante Moran with a copy of the disclosures in this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (“SEC”) and has requested that Plante Moran furnish the Company with a letter addressed to the SEC stating whether Plante Moran agrees with the above statements.
