a)Evaluation of Disclosure Controls and Procedures

As of December 31, 2025 (the end of the period covered by this report), we, including our chief executive officer and chief financial officer, evaluated the effectiveness and design and operation of our disclosure controls and procedures. Based on that evaluation, our management, including the chief executive officer and chief financial officer, concluded that our disclosure controls and procedures were effective at a reasonable assurance level in timely alerting management, including the chief executive officer and chief financial officer, of material information about us required to be included in periodic SEC filings. However, in evaluation of the disclosure controls and procedures, 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 management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

b)Changes in Internal Control over Financial Reporting

There were no changes in internal controls for the three months ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
