Change of Auditor

On April 10, 2025, Raytech Holding Limited (the “Company”) appointed Assentsure PAC (“Assentsure”) as its independent registered public accounting firm, effective on the same day. Assentsure replaces WWC, P.C. (“WWC”), the former independent registered public accounting firm, which the Company dismissed on April 9, 2025. The appointment of Assentsure was made after careful consideration and evaluation process by the Company and has been approved by the audit committee of the board of directors of the Company. The Company’s decision to make this change was not the result of any disagreement between the Company and WWC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

The audit report of WWC on the consolidated financial statements of the Company as of March 31, 2023 and 2024 and for the fiscal years ended March 31, 2023 and 2024 did not contain an adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, scope of accounting principles. Furthermore, during the Company’s two most recent fiscal years and through April 9, 2025, there were no disagreements with WWC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to WWC’s satisfaction, would have caused WWC to make reference to the subject matter of the disagreement in connection with its report on the Company’s financial statements for such periods. During the Company’s two most recent fiscal years and through April 9, 2025, there were no “reportable events” as that term is described in Item 16F(a)(1)(v) of Form 20-F, other than the material weaknesses reported by management in the annual report on Form 20-F filed with the U.S. Securities and Exchange Commission (the “Commission”) on July 30, 2024.

The Company has provided WWC with a copy of the above disclosure and requested that WWC furnish a letter addressed to the Commission stating whether or not it agrees with the above statements. A copy of WWC’s letter is filed hereto 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 Assentsure, neither the Company, nor someone on behalf of the Company, has consulted Assentsure regarding either (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 consolidated financial statements, and neither a written report was provided to the Company or oral advice was provided that Assentsure concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (b) any matter that was the subject of a disagreement as defined in Item 16F(a)(1)(iv) of Form 20-F and related instructions to Item 16F of Form 20-F, or any reportable events as described in Item 16F(a)(1)(v) of Form 20-F.
