Management’s Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer (who serves as our principal executive officer), and our Chief Operating Officer (who serves as our principal financial officer), as appropriate, to allow timely decisions regarding required disclosure. 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.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026 and, based on this evaluation, concluded that our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) was effective as of March 31, 2026.

Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2026, we completed the implementation of a new enterprise resource planning ("ERP") system and as a result, modified the design of certain existing internal controls, as well as implemented new controls and procedures impacted by the implementation of the new ERP system. Except for the implementation of the new ERP system, there were no other changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) during the quarter ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
