Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our principal executive officer and principal financial officer concluded that, as of September 30, 2025, our disclosure controls and procedures were not effective at the reasonable assurance level due to the material weaknesses in our internal control over financial reporting described below.

Previously Reported Material Weaknesses in Internal Control Over Financial Reporting

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

As disclosed in Part II, Item 1A, “Risk Factors” in this Quarterly Report on Form 10-Q, we previously identified material weaknesses in our internal control over financial reporting related to (i) inadequate segregation of duties within our financial reporting process, leading to certain duties being performed by the same individuals, (ii) an insufficient complement of personnel with an appropriate level of technical knowledge to properly account for significant transactions, and (iii) inadequate formalized processes and control activities to support the financial close and reporting process, including the review of financial information, account analysis, and journal entries. We have concluded that these material

weaknesses existed because we did not have the necessary business processes, systems, personnel, and related internal controls. The deficiencies identified did not result in a material misstatement to our financial statements.

Remediation Efforts to Address Previously Identified Material Weaknesses

We have taken and will continue to take action to remediate these material weaknesses, including:

•implementing processes and controls to better identify and manage segregation of duties risks;

•designing and implementing controls related to significant accounts and disclosures to achieve complete, accurate, and timely financial accounting, reporting, and disclosures, including controls over account reconciliations, segregation of duties, and the preparation and review of journal entries;

•continuing to hire additional accounting, finance, and operations resources with appropriate and sufficient technical expertise and to better allow for segregation of conflicting duties; and

•consulting with experts on technical accounting matters, internal controls, and in the preparation of our financial statements.

We believe we are making progress toward achieving effectiveness of our internal control over financial reporting. The actions that we are taking are subject to ongoing management review and audit committee oversight. 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 subsequently evaluated their design and effectiveness over a sufficient period of time, and management concludes, through testing, that these are operating effectively. We may also conclude that additional measures are required to remediate the material weaknesses in our internal control over financial reporting.

Changes in Internal Control Over Financial Reporting

Except for the remediation measures we are taking in connection with the material weaknesses described above, 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 the three months ended September 30, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitation 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.
