Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, have evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Report, our disclosure controls and procedures were not effective due to the material weaknesses in our internal control over financial reporting described below. However, after giving full consideration to such material weaknesses, and the additional analyses and other procedures that we performed to ensure that our unaudited Condensed Consolidated Financial Statements included in this Report were prepared in accordance with U.S. GAAP, our management has concluded that our unaudited Condensed Consolidated Financial Statements present fairly, in all material respects, our financial position, results of operations and cash flows for the periods disclosed in conformity with U.S. GAAP.

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 determined that the Company had the following material weaknesses in its internal control over financial reporting:

•The Company did not design and maintain an effective control environment commensurate with its financial reporting requirements. Specifically, the Company lacked a sufficient complement of resources with an appropriate level of accounting knowledge, experience and training to appropriately analyze, record and disclose accounting matters timely and accurately.

•The Company did not design and maintain effective controls related to the period-end financial reporting process, including, procedures and controls to achieve complete, accurate and timely financial accounting, reporting and disclosures.

Remediation Progress

We are continuing to remain focused on remediation of the remaining material weaknesses outlined above, and our ongoing remediation efforts include:

•The continued onboarding of U.S. GAAP and SEC reporting specialists to enhance the financial reporting function and establish a robust financial and system control framework; and

•The continued strengthening of controls around our financial accounting closing, reporting and disclosure processes.

We cannot assure you that the measures we have taken to date, and actions we may take in the future, will be sufficient to remediate the internal control deficiencies that led to our material weaknesses, that the material weaknesses will be remediated on a timely basis, or that additional material weaknesses will not be identified in the future.

Changes in Internal Control Over Financial Reporting

We are taking actions to remediate the material weaknesses relating to our internal control over financial reporting. Except as otherwise described above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
