CHANGES IN REGISTRANTS’ CERTIFYING ACCOUNTANT

(a)Previous Independent Registered Public Accounting Firm

The Company resolved not to reappoint WWC, P.C. (“WWC”) as our independent accountants. We informed WWC of this determination on December 18, 2025, which was effective December 18, 2025.

WWC, P.C. has rendered reports on our consolidated financial statements since the year ended September 30, 2022. During the fiscal years ended September 30, 2022, 2023 and 2024 through the date of this form 6-K, WWC has neither provided any adverse opinion or qualifications on our consolidated financial statements nor had a disagreement with the Company since their engagement on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements that, if not resolved to WWC’s satisfaction, would have caused WWC to make reference to the subject matter of the disagreement in connection with the audit of the Company’s consolidated financial statements.

None of the reportable events described under Item 16F(a)(1)(v) of Form 20-F occurred within period of the engagement of WWC.

We have provided WWC with a copy of this report prior to its filing with the Securities and Exchange Commission (the “SEC”). WWC has provided a letter to us, dated December 18, 2025 and addressed to the SEC, which is attached hereto as Exhibit 16.1 and is hereby incorporated herein by reference.

(b)Engagement of Independent Registered Public Accounting Firm

On December 18, 2025, we engaged WSJ & ARTNERS as our independent auditors for the fiscal year ended September 30, 2025.

During the two most recent fiscal years and in the subsequent period through the date of this report, we have not consulted with WSJ & PARTNERS with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that would have been rendered on our consolidated financial statements, or any other matters set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K.
