Evaluation of Disclosure Controls and Procedures

As of September 30, 2026, our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of 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 concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2026.

Remediation of Previously Identified Material Weakness

As previously disclosed, our management identified a material weakness in our internal control over financial reporting related to the design of effective controls over the review of the inputs in the calculation of net loss per share attributable to common stockholders.

In response to the material weakness, during the quarter ended March 31, 2026, management designed and implemented a control over the review of the inputs in the calculation of net loss per share attributable to common stockholders, including review by qualified accounting personnel. The control operated in connection with the preparation of our financial information for each of the quarters ended March 31, 2026, June 30, 2026 and September 30, 2026.

During the quarter ended September 30, 2026, management completed its evaluation of the design and operating effectiveness of the control. Based on this evaluation, management concluded, through testing, that the control was appropriately designed, implemented and operated effectively for a sufficient period of time and, accordingly, that the previously identified material weakness was remediated as of September 30, 2026.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2026 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.
