Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on such evaluation, our officers have concluded that, at June 30, 2026, our disclosure controls and procedures were effective in alerting them on a timely basis to material information required to be included in our periodic filings under the Exchange Act.
