Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, prior to filing this Annual Report on Form 10-K. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedures were effective at the reasonable assurance level.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating disclosure controls and procedures, our management recognizes that any system of controls, however well designed and operated, can provide only reasonable assurance, and not absolute assurance, that the desired control objectives of the system are met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events. Because of these and other inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals in all future circumstances. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act. Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2023, using the criteria established in “Internal Control—Integrated Framework” (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. Based on that assessment, our management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2023.

Remediation of Previously Identified Material Weaknesses in Internal Control

For the year ended December 31, 2022, we identified a material weakness in our internal controls over financial reporting related to the design and implementation of our IT general controls including a failure to document reviews of changes to user roles in our financial reporting systems and subsystems. During 2023, we fully implemented additional control procedures over changes to user roles in our financial reporting systems and subsystems and have operated effectively for a sufficient period of time to conclude that the previously identified material weakness has been remediated.

Attestation Report of Registered Public Accounting Firm

This annual report does not include an attestation report of our registered public accounting firm on our internal control over financial reporting due to an exemption established for “emerging growth companies” under the Jumpstart Our Business Startups (JOBS) Act.

Changes in Internal Control Over Financial Reporting

Except as otherwise disclosed, there was no change in our internal control over financial reporting that occurred during the fourth quarter ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
