Evaluation of Disclosure Controls and Procedures

The Company carried out an evaluation, with the participation of our management and under the supervision of our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined under Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2026.

Changes in Internal Control over Financial Reporting

As required by Rule 13a-15(d) of the Exchange Act, our management, including our Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of our internal control over financial reporting to determine whether any changes occurred during the quarter ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Merger, which was completed on September 2, 2025, has had a material impact on the financial position, results of operations, and cash flows of the combined company from the date of acquisition through June 30, 2026. The business combination also resulted in material changes in the combined company's internal control over financial reporting. The Company is in the process of designing and integrating policies, processes, operations, technology, and other components of internal control over financial reporting of the combined company. Management will monitor the implementation of new controls and test the operating effectiveness when instances are available in future periods.
