Limitations of the Effectiveness of Control

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 possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management conducted an evaluation, under the supervision and with the participation of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon that evaluation, our CEO and CFO concluded that, as of September 30, 2026, our disclosure controls and procedures were operating and effective at reasonable levels of assurance.

Changes in Internal Controls over Financial Reporting

During the quarter ending September 30, 2026, the Company implemented a new enterprise resource planning system (“ERP”) that will allow for more automated controls and enhance operational functionality. As a result of this implementation, we have made changes to our internal controls over financial reporting to address processes and procedures impacted by the ERP implementation.

Other than the changes associated with the ERP implementation noted above, there have been no changes in our internal controls over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15 under the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
