Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined under Securities Exchange Act Rule 13a-15(e), that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible 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 of June 30, 2025. Based upon their evaluation and subject to the foregoing, the principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance as of that date.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) of the Exchange Act) that occurred during the quarter ended June 30, 2025, which has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
