Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer 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. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and our principal financial officer, we carried out an evaluation of the effectiveness of our disclosure controls and procedures. Based on such evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the quarterly period ended June 30, 2026.
