Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

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 of the design and operation of our disclosure controls and procedures as of September 30, 2024. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of September 30, 2024 because of the material weakness in internal control over financial reporting at December 31, 2023 that we previously identified in Item 9A. “Controls and Procedures” of our 2023 Form 10-K had not been fully remediated at September 30, 2024.

Notwithstanding the material weakness in internal control over financial reporting, our management has concluded that our condensed consolidated financial statements included in the Quarterly Report on Form 10-Q are fairly stated in all material respects in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Previously Reported Material Weakness

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.

As described in more detail in Item 9A. “Controls and Procedures” of our 2023 Form 10-K, the material weakness identified related to the fact that our accounting and operating systems lacked controls over access, and program change management that are needed to ensure access to financial data is adequately restricted to appropriate personnel, including consideration of the appropriate segregation of duties. As a result, it is possible that our business process controls that depend on the accuracy and completeness of data or financial reports generated by our information technology system could be adversely affected due to the lack of operating effectiveness of the information technology general controls (“ITGCs”).

Remediation Plan

Our management is actively engaged and committed to taking the steps necessary to remediate the material weakness over user access and program change management in order to establish a strong internal control environment. Remediation actions undertaken during 2023 and planned are described in more detail in Item 9A. “Controls and Procedures” of our 2023 Form 10-K.

While significant progress has been made to strengthen the design and operating effectiveness of our ITGCs, management has concluded that as of September 30, 2024, there was not a sufficient period of time available to sufficiently test nor conclude that enhanced internal controls were fully implemented and operating effectively. We will continue to monitor the effectiveness of ITGC remediation actions in connection with future assessments of the effectiveness of internal control over financial reporting and disclosure controls and procedures. Assessment results will be used to validate the efficacy of our ITGC remediation efforts and identify any additional actions necessary to ensure ongoing design and operating effectiveness.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the nine months ended September 30, 2024 covered by this Quarterly Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We are continuing to take steps to remediate the material weakness in our internal control over financial reporting, as discussed above.

Inherent Limitation on the Effectiveness of Internal Control

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures, or our internal controls, will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our Company have been detected.
