As previously disclosed in the Current Report on Form 8-K filed by XTI Aerospace, Inc. (the “Company”) with the Securities and Exchange Commission on March 27, 2025, on March 24, 2025, as a result of the acquisition by CBIZ CPAs P.C. (“CBIZ”) of the attest business of Marcum LLP (“Marcum”), the Audit Committee of the Company’s Board of Directors approved the engagement of CBIZ as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025, subject to the effectiveness of Marcum’s resignation upon the filing of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “Form 10-K”) and the execution of an engagement letter by the Company and CBIZ. Subsequent to the filing of the Form 10-K, on April 21, 2025, the Company and CBIZ entered into an engagement letter. Accordingly, CBIZ’s appointment as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025 was effective April 21, 2025.

During the fiscal years ended December 31, 2024 and 2023 and the subsequent interim period through April 21, 2025, neither the Company nor anyone on the Company’s behalf consulted with CBIZ regarding (i) the application of accounting principles to a specific completed or contemplated transaction or regarding the type of audit opinions that might be rendered by CBIZ on the Company’s consolidated financial statements, and CBIZ did not provide any written or oral advice that was an important factor considered by the Company in reaching a decision as to any such accounting, auditing, or financial reporting issue or (ii) any matter that was either 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 defined in Item 304(a)(1)(v) of Regulation S-K).
