What the latest filing says

A material weakness is a control deficiency, or combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a misstatement of the registrant's financial statements will not be prevented or detected on a timely basis. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures as of June 30, 2026 were not effective as of the period covered by this Quarterly Report due to material weaknesses in internal controls over financial reporting. For more information on material weaknesses identified by management, please refer to our Form 10-K filed on February 27, 2026 for the year ended Decembe [...]
