4 terms

independent registered public accounting firm financial

"BPM notified Datavault AI Inc. of its decision to resign as the Company’s independent registered public accounting firm"

An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.

reportable events regulatory

"there were no reportable events (as that term is described in Item 304(a)(1)(v) of Regulation S-K)"

Reportable events are significant incidents or changes a company is legally required to disclose to regulators and the public, such as major safety problems, legal actions, financial irregularities, or management changes. They matter to investors because these events can alter a company’s risk profile or future performance, much like a dashboard warning light signals a problem that could affect a car’s safety or reliability. Timely disclosure helps investors make informed decisions and maintain market fairness.

Item 304(a)(1)(iv) of Regulation S-K regulatory

"no disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with BPM"

Emerging growth company regulatory

"Emerging growth company"

An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.

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.
