Changes in Registrant’s Certifying Accountant

(a) Dismissal of Previous Independent Registered Public Accounting Firm

On June 24, 2026, Dominari Holdings Inc. (the “Company”), with the approval of the audit committee of the board of directors of the Company (the “Audit Committee”), dismissed CBIZ CPAs P.C. (“CBIZ CPAs”) as the Company’s independent registered public accounting firm.

As previously disclosed in a Current Report on Form 8-K filed on April 30, 2025, on April 25, 2025, Marcum LLP was dismissed, and CBIZ CPAs was appointed as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2025.

For the period from April 25, 2025 through the date of CBIZ CPAs’ dismissal, the report of CBIZ CPAs on the financial statements did not contain an adverse opinion or a disclaimer of opinion, or was qualified or modified as to uncertainty, audit scope, or accounting principles. There were no disagreements, as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto, between the Company and CBIZ CPAs 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 CBIZ CPAs, would have caused CBIZ CPAs to make reference to the subject matter of the disagreements in connection with its audit reports on the Company’s financial statements.

For the period from April 25, 2025 through the date of CBIZ CPAs’ dismissal, there were no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K except for the following material weaknesses in our internal control over financial reporting related to: (i) the lack of personnel to ensure the books and records are closed accurately and on a timely basis, (ii) lack of sufficient review over the accounting for certain transactions recorded at fair value, (iii) the lack of appropriate segregation of duties, (iv) certain general information technology control deficiencies regarding user access provisioning and administrative access review, and (v) insufficient documentation to support and evidence the design and implementation of controls.

The Company provided CBIZ CPAs with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (“SEC”) and requested that CBIZ CPAs furnish the Company with a letter addressed to the SEC stating whether it agrees with the above statements and, if it does not agree, the respects in which it does not agree. A copy of the letter furnished by CBIZ CPAs, dated June 26, 2026, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b) Appointment of New Independent Registered Public Accounting Firm

On June 24, 2026, the Company engaged Grassi & Co., CPAs, P.C. (“Grassi”) to serve as its independent registered public accounting firm for the fiscal year ending December 31, 2026.

During the Company’s fiscal years ended December 31, 2025 and 2024, and during the interim period from the end of the most recently completed fiscal year through June 24, 2026, the date of engagement of Grassi, neither the Company nor anyone on behalf of the Company consulted with Grassi regarding (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements as to which the Company received a written report or oral advice that Grassi concluded was an important factor considered by the Company in reaching a decision on any accounting, auditing or financial reporting issue; or (b) any matter that was the subject of a disagreement or a reportable event as defined in Items 304(a)(1)(iv), and the related instructions thereto, and (v), respectively, of Regulation S-K.
