Disclosure Controls and Procedures

Disclosure controls are procedures designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, such as this Quarterly Report on Form 10-Q, are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and principal financial officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and implemented, can provide only reasonable, not absolute, assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Under the supervision and with the participation of our management, including our CEO, who is currently also acting as our CFO for this purpose, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) under the Exchange Act as of the end of the period covered by this report. Based on that evaluation, our management, including our CEO and CFO, concluded that our disclosure controls and procedures were not effective as of September 30, 2025, as the result of the material weakness in our internal control over financial reporting discussed below, which is currently being remediated.

Management believes the consolidated financial statements included in this Quarterly Report on Form 10-Q present fairly, in all material respects, the Company’s financial condition, results of operations and cash flows for each of the periods presented in this report in conformity with U.S. GAAP.

Material Weakness in Internal Control over Financial Reporting

As of December 31, 2023, we had identified a material weakness in our internal control over financial reporting, relating to the appropriate review of accounting positions for certain significant transactions. Specifically, (a) the Company did not have sufficient resources with the adequate technical skills to identify and evaluate specific accounting positions and conclusions, and (b) the Company had inadequate processes and controls to ensure appropriate level of precision of review related to our financial statement footnote disclosures.

Remediation Efforts to Address Material Weakness

Management is committed to maintaining a strong internal control environment. In response to the identified material weakness, management, with the oversight of the Audit Committee of the Board of Directors, has taken actions to remediate the material weakness in internal control over financial reporting by (a) hiring a controller with responsibility for monitoring the performance of controls by control owners, (b) continuing our evaluation of the skills and experience of our existing personnel with respect to public company experience and appropriate level of expertise in the respective areas of accounting, SEC financial reporting and associated internal controls commensurate with the type, volume and complexity of our accounting operations, transactions and reporting requirements, and (c) engaging accounting advisory consultants to provide additional depth and breadth in our SEC financial reporting and technical accounting functions, which consultants we expect to continue to utilize until we have ensured that our internal personnel have the appropriate expertise and experience. In addition, we have reinforced the importance of adherence to Company policies regarding control performance and related documentation with control owners, identified training and resource needs for control owners, and developed monitoring activities to validate the performance of controls by control owners.

The Company anticipates that the actions described above and resulting improvements in controls will strengthen the Company’s processes, procedures and controls related to management’s review of accounting positions for significant and complex transactions and will address the related material weakness. However, the material weakness cannot be considered remediated until the applicable control has operated for a sufficient period of time, and management has concluded, through testing, that the control is operating effectively.

Changes in Internal Control over Financial Reporting

Other than the ongoing remediation efforts of the material weakness described above, there were no changes during the three months ended September 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
