Changes in Registrant’s Certifying Accountant

On May 21, 2026, RBSM LLP (“RBSM”) notified the Audit Committee of the board of directors (the “Audit Committee”) of MDJM LTD (the “Company”) of its resignation as the Company’s independent registered public accounting firm, effective as of May 21, 2026.

On May 22, 2026, the Audit Committee approved the engagement of Tang Qian & Associates, PLLC (“TQ&A”) as the Company’s independent registered public accounting firm, and the engagement of TQ&A became effective as of May 22, 2026. TQ&A has been engaged to audit the consolidated financial statements of the Company and its subsidiaries for the fiscal year ending December 31, 2026.

RBSM’s audit reports 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, and were not qualified or modified as to uncertainty, audit scope, or accounting principles. During the Company’s two most recent fiscal years and through May 21, 2026, there were no disagreements with RBSM on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to RBSM’s satisfaction, would have caused RBSM to make reference to the subject matter of the disagreements in connection with its audit reports on the Company’s consolidated financial statements for such periods. During the Company’s two most recent fiscal years and through May 21, 2026, there were no “reportable events” as described in Item 16F(a)(1)(v) of Form 20-F.

The Company provided RBSM with a copy of the foregoing disclosure and requested that RBSM furnish a letter addressed to the U.S. Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of RBSM’s letter is filed hereto as Exhibit 16.1.

During the Company’s two most recent fiscal years and any subsequent interim period prior to the engagement of TQ&A, neither the Company nor anyone on its behalf consulted TQ&A regarding either: (i) the application of accounting principles to a specified transaction, whether completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and no written report or oral advice was provided to the Company that TQ&A concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; or (ii) any matter that was the subject of a “disagreement,” as defined in Item 16F(a)(1)(iv) of Form 20-F and the related instructions thereto, or a “reportable event,” as described in Item 16F(a)(1)(v) of Form 20-F.

Incorporation by Reference
