Change of Auditor

On February 10, 2026, Baird Medical Investment Holdings Limited (the “Company”), upon the approval and ratification of the board of directors of the Company (the “Board”) and the audit committee of the Board (the “Audit Committee”), dismissed Kreit & Chiu CPA LLP (“Kreit & Chiu”), the former independent registered public accounting firm of the Company, effective on February 10, 2026, and appointed Guangdong Prouden CPAs GP (the “New Auditor”) to serve as its independent registered public accounting firm, effective on February 10, 2026, for the year ended December 31, 2025.

Kreit & Chiu’s reports on the Company’s financial statements for the fiscal years ended December 31, 2024 did not contain any adverse opinion or disclaimers of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

Furthermore, during the fiscal years ended December 31, 2024 and through February 10, 2026, there were no disagreements, as defined in Item 16F(a)(1)(iv) of Form 20-F, with Kreit & Chiu 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 Kreit & Chiu, would have caused Kreit & Chiu to make reference to the subject matter of the disagreements in connection with its reports on the Company’s financial statements for such year. In addition, during this time, there were no “reportable events,” as defined in Item 16F(a)(1)(v)(A)-(D) of Form 20-F, except for the material weaknesses related to the Company’s internal control over financial reporting, including (i) lack of sufficient financial reporting and accounting personnel with appropriate knowledge of U.S. GAAP and SEC reporting requirements to properly address certain accounting issues and to prepare and review financial statements and related disclosures in accordance with U.S. GAAP and SEC reporting requirements; and (ii) lack of comprehensive accounting policies and procedures manual in accordance with U.S. GAAP and documented controls which enable management and other personnel to understand and carry out their internal control responsibilities.

The Company provided Kreit & Chiu with a copy of the above disclosure and requested that Kreit & Chiu furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of Kreit & Chiu’s letter is filed as Exhibit 16.1 to this Form 6-K.

During the two most recent fiscal years and any subsequent interim periods prior to the engagement of the New Auditor, neither the Company, nor someone on behalf of the Company, has consulted the New Auditor regarding any of the matters described in Item 16F(a)(2)(i) and (ii) of Form 20-F. The New Auditor is aware of the material weaknesses described above and understands it is a reportable event.
