Disclosure Controls and Procedures

As of the end of the period covered by this Annual Report, we evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act), and management necessarily applied its judgment in assessing the costs and benefits of such controls and procedures, which by their nature, can provide only reasonable assurance about management’s control objectives. Our disclosure controls and procedures have been designed to provide reasonable assurance of achieving the desired control objectives. However, you should note that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Based upon the foregoing evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2025, our disclosure controls and procedures were effective and operating to provide reasonable assurance that we record, process, summarize and report the information we are required to disclose in the reports that we file or submit under the Exchange Act within the time periods specified in the rules and forms of the SEC, and to provide reasonable assurance that we accumulate and communicate such information to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions about required disclosure.

Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f). We have set forth management’s annual report on internal control over financial reporting and the independent registered public accounting firm’s report on the effectiveness of our internal control over financial reporting in Part II, Item 8 of this Annual Report, and we incorporate those reports by reference.

Changes in Internal Control Over Financial Reporting

We made no changes in our internal control over financial reporting during the fourth quarter of 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
