Item 4.01. Changes in Registrant’s Certifying Accountant. 

On August 15, 2023, the Audit Committee of the Board of Directors of Xtant Medical Holdings, Inc. (the “Company”) appointed Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, and in connection therewith dismissed Plante & Moran, PLLC (“Plante Moran”), as the Company’s independent registered public accounting firm, subject to Grant Thornton LLP’s standard client acceptance procedures, which were completed on August 18, 2023. The decision to appoint Grant Thornton as the Company’s new independent registered public accounting firm was the result of a request for proposal process after Plante Moran notified the Audit Committee that Plante Moran is evaluating whether to continue its Securities and Exchange Commission audit practice in the Company’s primary industry.

During the two most recent fiscal years ended December 31, 2022 and 2021, and through the subsequent interim period preceding the Company’s appointment of Grant Thornton as the Company’s independent registered public accounting firm, neither the Company, nor anyone on its behalf, consulted Grant Thornton regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the consolidated financial statements of the Company, and no written report or oral advice was provided to the Company by Grant Thornton that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

The audit reports of Plante Moran on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2022 and 2021 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 two most recent fiscal years ended December 31, 2022 and 2021, and through the subsequent interim period preceding Plante Moran’s dismissal, (1) there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and Plante Moran on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Plante Moran, would have caused Plante Moran to make reference thereto in its report on the Company’s consolidated financial statements for the years ended December 31, 2022 and 2021, and (2) there were no “reportable events” as such term is defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided Plante Moran with a copy of the disclosures set forth in this Current Report on Form 8-K and requested that Plante Moran furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission stating whether or not Plante Moran agrees with the statements related to Plante Moran made by the Company in this Current Report on Form 8-K and, if not, stating the respects in which it does not agree. A copy of the response letter from Plante Moran is filed as Exhibit 16.1 to this Current Report on Form 8-K.
