On April 7, 2025, TransAct Technologies Incorporated (the “Company”) was notified by Marcum LLP (“Marcum”) that Marcum resigned as the Company’s independent registered public accounting firm, and on April 8, 2025, the Audit Committee of the Board of Directors of the Company (the “Audit Committee”) approved the resignation.

On November 1, 2024, CBIZ CPAs P.C. (“CBIZ”) acquired the attest business of Marcum. Substantially all of the partners and staff that provided attestation services with Marcum joined CBIZ.

The reports of Marcum on the Company’s financial statements for the fiscal years ended December 31, 2024 and 2023 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 did not contain an adverse opinion or a disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal years ended December 31, 2024 and 2023 and the subsequent interim period through April 7, 2025, there were no (1) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and Marcum on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure that would have caused Marcum to make reference to the subject matter of such a disagreement in connection with its audit reports on the Company’s financial statements for such years, or (2) reportable events (as described in Item 304(a)(1)(v) of Regulation S-K).

The Company has provided Marcum with a copy of the foregoing disclosures that the Company is making in this Current Report on Form 8-K prior to its filing and requested, in accordance with applicable practices, that Marcum furnish a letter addressed to the Securities and Exchange Commission stating whether Marcum agrees with the statements made herein. Attached as Exhibit 16.1 is a copy of Marcum’s letter, dated April 9, 2025, stating that it agrees with such statements.

On April 8, 2025, with the approval of the Audit Committee, CBIZ was engaged as the Company’s new independent registered public accounting firm for the fiscal year ending December 31, 2025.

During the fiscal years ended December 31, 2024 and 2023 and the subsequent interim period through April 8, 2025, neither the Company nor anyone on its behalf consulted with CBIZ regarding (1) the application of accounting principles to a specified transaction, completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that CBIZ concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (2) 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 described in Item 304(a)(1)(v) of Regulation S-K).
