Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of June 30, 2026, management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, have evaluated our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, solely as a result of the material weaknesses in our internal control over financial reporting described below, as of June 30, 2026, our disclosure controls and procedures were not effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There are no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended June 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Previously Reported Material Weakness

In connection with the preparation of our financial statements for the years ended December 31, 2024 and 2023, our management and our independent auditors identified material weaknesses in the design and operating effectiveness of our internal control over financial reporting, which remained unremediated as of December 31, 2025. The material weaknesses identified by our management and our independent auditors relate to (i) a lack of appropriately designed, implemented and documented procedures and controls, and (ii) deficiencies in the segregation of duties.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

Management has initiated and continues to implement a remediation plan to address the material weaknesses described above. During the year ended December 31, 2025 and through the quarter ended June 30, 2026, we implemented changes to our internal control over financial reporting, including enhancements to our control environment, improvements to process-level controls, and formal documentation of policies, processes, risks, and controls. Segregation of duties has been enhanced across the control environment and financial reporting systems through system automation, strengthened month-end controls, and enhanced review procedures. Management has commenced testing and is currently validating the operating effectiveness of these enhanced controls, and remediation actions are progressing as planned.

While we believe that these efforts will improve our internal control over financial reporting, the design and implementation of our remediation is ongoing and will require validation and testing of the design and operating effectiveness of our internal controls over a sustained period of financial reporting cycles. The actions that we are taking are subject to ongoing senior management review, as well as oversight by the Audit and Risk Committee. We will not be able to conclude whether the steps we are taking will fully remediate the material weaknesses in our internal control over financial reporting until we have completed our remediation efforts and subsequent evaluation of their effectiveness.
