Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of the Company’s Chief Executive Officer and Principal Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules

13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company 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 SEC’s rules and forms. Disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Based upon the controls evaluation and the material weakness described below, the Company’s Chief Executive Officer and Principal Financial Officer have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures are ineffective.

There have not been any changes in the Company’s 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 Company’s fiscal quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Management of the Company, including the Chief Executive Officer and the Principal Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) under the Exchange Act. The Company’s internal controls were designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation and fair presentation of published financial statements.

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 with respect to financial statement preparation and presentation.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control – Integrated Framework (2013 framework). Based on our assessment and the material weakness described below, we believe that, as of December 31, 2023, the Company’s internal control over financial reporting is ineffective based on those criteria.

A material weakness is 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 a company’s annual or interim financial statements will not be prevented or detected on a timely basis. Our financial statement close process controls which relate to all financial statement accounts, did not consistently operate effectively or lacked appropriate evidence, to ensure account reconciliations, transactions and journal entries were performed or reviewed at the appropriate level of precision and on a timely basis. As part of this deficiency, we identified deficiencies associated with our revenue transaction cycle. These control deficiencies could result in a material misstatement of our accounts or disclosures that would not be prevented or detected on a timely basis, and accordingly, we determined that these control deficiencies in aggregate constitute a material weakness.

Remediation Plan

As disclosed in previous filings, we previously identified a material weakness in our internal control over financial reporting. Due to challenges in maintaining necessary accounting staffing levels, this material weakness has not been remediated as of December 31, 2023, as disclosed above, and our expected timeline for completing the remediation of this material weakness has extended beyond our original estimates.

We have developed a plan for remediation of the material weakness, including developing and maintaining appropriate management review and process level controls. Control weaknesses are not considered remediated until new internal controls have been operational for a period of time, are tested and management concludes that these controls are operating effectively. We will continue to monitor the effectiveness of our remediation measures in connection with our future assessments of the effectiveness of internal control over financial reporting and disclosure controls and procedures. We will make any changes to the design of our plan and take such other actions that we deem appropriate given the circumstances. We expect to complete the remediation process by the end of the fourth quarter of 2024.

The establishment of effective internal controls over financial reporting and disclosure controls and procedures is the responsibility of the Company. As a non-accelerated filer, the Company is not required to obtain an attestation on internal controls over financial reporting.
