Item 4.01. Changes in Registrant’s Certifying Accountant.

On June 15, 2026, BPM LLP (“BPM”) notified Datavault AI Inc. (the “Company”) of its decision to resign as the Company’s independent registered public accounting firm effective immediately. The Company is currently in the process of selecting a successor independent registered public accounting firm and, as required by the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), will disclose its engagement of a new independent registered public accounting firm once the selection process has been completed.

The reports of BPM on the Company’s consolidated financial statements for the fiscal years ended December 31, 2025 and 2024 did not contain an adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope, or accounting principles. During the fiscal years ended December 31, 2025 and 2024, and in the subsequent interim period through June 15, 2026, there have been no disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with BPM on any matters of accounting principles or practices, financial statement disclosure or auditing scope and procedure, which disagreements, if not resolved to the satisfaction of BPM, would have caused BPM to make reference thereto in its reports.

During the fiscal years ended December 31, 2025 and 2024, and in the subsequent interim period through June 15, 2026, there were no reportable events (as that term is described in Item 304(a)(1)(v) of Regulation S-K).

The Company provided a copy of the foregoing disclosures to BPM and requested that BPM furnish it with a letter addressed to the SEC stating whether BPM agrees with the above statements. A copy of BPM’s letter, dated June 22, 2026 is filed as Exhibit 16.1 to this Current Report on Form 8-K.
