Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e)) under the Exchange Act that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated, as of the end of the period covered by this Quarterly Report, the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2025, our disclosure controls and procedures were not effective at the reasonable assurance level due to the material weakness in internal control over financial reporting which existed as of September 30, 2025, relating to the documentation of accounting policies and procedures, particularly relating to the correct application of complex accounting measures as previously reported in our 2025 Annual Report.

A material weakness is defined as a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Management has concluded that we did not maintain effective disclosure controls and procedures due to the material weakness in internal control over financial reporting which existed as of September 30, 2025, relating to the documentation of accounting policies and procedures, particularly relating to the correct application of complex accounting measures.

Remediation Efforts

The measures that we are undertaking to remediate the material weakness in internal control over financial reporting have and will include: (a) hiring qualified internal control personnel or consultants to manage the implementation of internal control policies, procedures and improvement of the internal audit function, as applicable; (b) developing and implementing written policies and procedures for accounting and financial reporting that meet the standards applied to public companies listed in the United States; and (c) conducting internal control training to management, key operations personnel and the accounting department, so that management and relevant personnel understand the requirements and elements of internal control over financial reporting mandated by the US securities laws.

We believe we have made progress in accordance with our remediation plan even though the material weaknesses will not be considered remediated until we have completed implementing the necessary additional applicable controls and operate with them for a sufficient period of time to allow management and our auditors to concluded that these controls are operating effectively.

We cannot determine when our remediation plan will be fully completed and we cannot provide any assurance that these remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of these efforts.

Changes in Internal Control over Financial Reporting

Other than the remediation of the material weakness discussed above, there were no changes in our internal controls over financial reporting (as such term is defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) that occurred during three months ended September 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
