Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness the design and operation of our disclosure controls and procedures prior to the filing of this Quarterly Report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer assessed the effectiveness of our internal control over financial reporting as of September 30, 2024, and determined that our internal control over financial reporting was not effective at a reasonable assurance level due to the material weaknesses in our internal control over financial reporting related to the inadequate design and operation of management’s review controls over valuation reports prepared by third-party specialists in conjunction with the accounting for certain debt and equity instruments, resulting in the conclusion that the Company’s internal control over financial reporting and the Company’s disclosure controls and procedures were not effective as of September 30, 2024.

We are currently implementing our remediation plan to address the material weaknesses identified above. Such measures include:

1. additional review of third-party valuation reports utilized in the accounting for certain debt and equity instruments;

2. additional review of the manual journal entries based on externally generated reports and agreements with regard to accounting issues in certain debt and equity instruments;

3. enhanced oversight controls on the work performed by third-party specialists.

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we detected all of our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Changes in Internal Control over Financial Reporting

Other than in connection with executing upon the continued implementation of the remediation measures referenced above, there have been no changes in our internal controls over financial reporting during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
