Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, under the supervision and with the participation of our management, including our CEO and chief financial officer (“CFO”), we evaluated the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the “Exchange Act”). Based on that evaluation, management, including our CEO and CFO, has concluded that our disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information we are required to disclose is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to the Company’s management, including the CEO and the CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in internal controls. There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) that occurred during the fourth quarter of our year ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting. Management, under the supervision of the CEO and CFO, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our management has assessed the effectiveness of our 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”) Internal Control - Integrated Framework (2013 Framework). Based on the assessment, management has concluded that, as of December 31, 2023, our internal control over financial reporting was effective based on those criteria.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. As such, even those systems determined to be effective can provide only reasonable assurance of achieving their control objectives.

We intend to review and evaluate the design and effectiveness of our disclosure controls and procedures and internal control over financial reporting on a regular basis, to improve these controls and procedures over time, and to correct any deficiencies that may be discovered. Future events affecting our business may cause us to modify our controls and procedures.

Our independent registered public accounting firm has issued an attestation report regarding its assessment of the effectiveness of our internal control over financial reporting as of December 31, 2023.
