Evaluation of Disclosure Controls and Procedures

Pursuant to Rules 13a-15(b) and 15d-15(b) under the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this report. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of our controls and procedures relative to their costs.

Based on that evaluation, our CEO and CFO concluded that, as of September 30, 2025 our disclosure controls and procedures were effective at the reasonable assurance level to ensure that the information required to be disclosed in the reports required to be filed or submitted under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and (ii) accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2025 that materially affected, or are reasonably likely to materially affect, internal control over financial reporting.
