(a) Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”), that are designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act, is recorded, processed, summarized, and reported within the time periods specified by the Commission’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act are properly recorded, processed, summarized and reported within the time periods required by the Commission’s rules and forms.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer (principal executive officer) and Corporate Controller (principal financial officer), of the effectiveness of the design and operation of these disclosure controls and procedures, as such term is defined in Exchange Act Rule 13a-15(e), as of June 30, 2026 . Based on this evaluation, the Chief Executive Officer (principal executive officer) and Corporate Controller (principal financial officer) concluded that our disclosure controls and procedures were not effective as of June 30, 2026, the end of the period covered by this Quarterly Report on Form 10-Q, due to the material weaknesses described below.

(b) Management’s Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness of internal control over financial reporting to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management has assessed the effectiveness of our internal control over financial reporting as of June 30, 2026. In making our assessment of the effectiveness of internal control over financial reporting, management used the criteria set forth inInternal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

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 material misstatement of the registrant’s annual or interim financial statements will not be prevented or detected on a timely basis. As a result of our evaluation of our internal control over financial reporting, management identified the following material weaknesses in our internal control over financial reporting:

Accordingly, management concluded that we did not maintain effective internal control over financial reporting as of June 30, 2026.

Plan for Remediation of Material Weakness

The Company intends to remediate the material weakness through measures that are expected to include engaging outside technical accounting resources with respect to significant and unusual transactions, including equity financing arrangements; enhancing management review procedures over the application of new accounting standards and the timing of recognition of non-cash charges; and periodic reporting to the Audit Committee on remediation progress. As management continues to evaluate and refine our internal control framework, additional steps may be taken to address any remaining deficiencies or to further strengthen remediation measures already in place.

(c) Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
