On March 24, 2026, the Board of the Company dismissed Marcum Asia CPAs LLP (“Marcum Asia”) and approved the appointment of Ernst & Young LLP, located in Singapore (“EY SG”) as the Company’s independent registered public accounting firm for the audits of the Company’s consolidated financial statements to be filed with the SEC. The change of the Company’s independent registered public accounting firm was and made after a review process conducted by Audit Committee.

Marcum Asia’s audit reports on the Company’s consolidated financial statements for the years ended March 31, 2025 and 2024 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles as defined in Item 16F(a)(1)(ii)of Form 20-F. During the two most recent fiscal years and through the subsequent interim period preceding the dismissal, there were no (i) disagreements (as defined in Item 16F(a)(1)(iv) to Form 20-F and the related instructions thereto) between the Company and Marcum Asia on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, any of which, if not resolved to Marcum Asia’s satisfaction, would have caused Marcum Asia to make reference thereto in its audit report on the financial statements of the Company for such period, or (ii) “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 accounting staff and resources with appropriate knowledge of GAAP and SEC reporting and compliance requirements to design and implement formal period-end financial reporting policies and procedures to address complex technical accounting issue in accordance with GAAP and the SEC requirements., and (ii) lack of information technology general controls in the areas of IT policies and procedures, user provisioning and termination, privileged access and service organization monitoring who are responsible for change management over certain core business system and accounting system. There were no disputes or disagreements between the Company and Marcum Asia during the time it was the Company’s independent registered public accounting firm through the date of dismissal.

The Company has provided Marcum Asia with a copy of the foregoing disclosure and has requested that Marcum Asia review such disclosure and provide a letter addressed to the SEC as specified by Item 16F(a)(3) of Form 20-F. Attached as Exhibit 16.1 is a copy of Marcum Asia’s letter addressed to the SEC relating to the statements made by the Company in this Report on Form 6-K.
