Report of Disclosure Controls and Procedures

Regulations under the Exchange Act require public companies to maintain “disclosure controls and procedures,” which are defined as controls and other procedures that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. 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 principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we have evaluated the effectiveness, the design and operations of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the principal executive officer and principal financial officer determined that as of December 31, 2023, the Company’s disclosure controls and procedures were ineffective as a result of material weaknesses in our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, the Company conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in* Internal Control - Integrated Framework* issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013 (COSO).

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Despite these controls, because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives. Furthermore, smaller reporting companies, like us, face additional limitations. Smaller reporting companies employ fewer individuals and can find it difficult to employ resources for complicated transactions and effective risk management. Additionally, smaller reporting companies tend to utilize general accounting software packages that lack a rigorous set of software controls.

Our management, including our Chief Executive Officer and Principal Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2024 based on the criteria established in “Internal Control - Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. This evaluation included review of the documentation of controls, evaluation of the design effectiveness of controls, testing of the operating effectiveness of controls and a conclusion on this evaluation. Based on this evaluation, our management concluded our internal control over financial reporting was not effective as of December 31, 2024. The ineffectiveness of our internal control over financial reporting was due to the following material weaknesses which are indicative of many small companies: (i) lack of a sufficient complement of personnel commensurate with the Company’s reporting requirements; and (ii) insufficient written documentation or training of our internal control policies and procedures which provide staff with guidance or framework for accounting and disclosing financial transactions.

This annual report does not include an attestation report of our registered public accounting firm regarding our internal controls over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to Section 404(c) of the Sarbanes-Oxley Act that permit us to provide only management’s report in this annual report.

Despite the existence of the material weaknesses above, we believe that our consolidated financial statements contained in this Form 10-K fairly present our financial position, results of operations and cash flows as of and for the periods presented in all material respects.

Changes in Internal Control over Financial Reporting

Except as discussed below, there have been no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15 (f) under the Exchange Act) during the fourth quarter of 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Material Weaknesses

In connection with our annual audit for the year ended December 31, 2024, management determined that controls as described above constitute material weaknesses in disclosure controls and procedures and internal control over financial reporting. As a result, it was determined that control deficiencies that constitutes material weaknesses in the design and operation of our internal control over financial reporting was present. Management believes that these material weaknesses did not have an effect on our financial results. However, management believes that the lack of these items results in ineffective internal controls, which could result in a material misstatement in our financial statements in future periods.

The material weakness described above did not result in a material misstatement to the consolidated financial statements as of December 31, 2024 and the year then ended presented in this Annual Report on Form 10-K; however, the material weakness did result in a material misstatement to the consolidated financial statements during the year ended December 31, 2022 which resulted in the restatement of the consolidated financial statements as of and for the years ended December 31, 2023 and December 31, 2022, and as of and for the interim quarterly periods during the years ended December 31, 2024 and 2023 presented in this Annual Report on Form 10-K and labeled as restated.

Remediation

During 2023, certain actions were taken to address certain aspects of the material weaknesses disclosed above. Effective as of March 1, 2023, we retained a certified public accountant to assist with bookkeeping and accounting services, and as of September 1, 2023, we hired a new financial consulting firm to assist us in bookkeeping and preparing financial statements for our SEC filings, assist us in evaluating our internal controls over financial reporting and assist us in other related matters. Such new firm has replaced the financial consulting firm which had been provided service to the Company since the fourth quarter of 2019 and such new firm has taken on additional responsibilities. In addition, as of November 1, 2023, we appointed a new Chief Financial Officer with over 15 years of experience in accounting and financial control for both private and publicly listed companies to provide fractional Chief Financial Officer services. We also have made efforts in 2023 and 2024 to strengthen our overall control environment by improving our documented internal control policies and staff training.

Although we believe that these efforts effectively strengthen our disclosure control processes and procedures, our management team intends to continue to actively plan for and implement additional control procedures to improve our overall control environment and expect these efforts to continue throughout 2025 and beyond. Due to the nature of the remediation process, the need to have sufficient resources to retain additional staff to devote to such efforts and further segregate duties, and the need to allow adequate time after implementation to evaluate and test the effectiveness of the controls, no assurance can be given as to the timing of achievement of remediation.
