(c)Changes in Internal Control Over Financial Reporting

Our management, with the participation of our principal executive officer and our principal financial officer, have evaluated any changes in our internal control over financial reporting that occurred during the three months ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. During the third quarter of 2024, we completed the implementation of a new enterprise resource planning (“ERP”) system. As a result, we have modified or implemented certain annual internal controls over financial reporting to address the new control environment and processes associated with the new ERP system. There were no other changes in our internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
