Management’s Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), under the supervision and with the participation of management, including our Chief Executive Officer and our President and Chief Financial Officer, we have carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Report. Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required to disclose in reports that are filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and our President and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified by the SEC. Our Chief Executive Officer and President and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2026.

Changes in Internal Control Over Financial Reporting

There has been no change in the Company’s internal control over financial reporting during the quarter ended September 30, 2026 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, as specified above. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met.
