Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are those controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), to allow timely decisions regarding required disclosure.

The Company’s management, with the participation of its Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), evaluated the effectiveness of the Company’s disclosure controls and procedures as defined by Rule 13a-15(e) of the Exchange Act defined above, as of March 27, 2026, the end of the period covered by this Quarterly Report on Form 10-Q (the “Evaluation Date”). Based on that evaluation, the Company’s management, with the participation of the Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer) concluded that the Company’s disclosure controls and procedures, as of the Evaluation Date, were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), as appropriate to allow timely decisions regarding required disclosure.
