Evaluation of Disclosure Controls and Procedures

Disclosure controls are procedures that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this Report, is recorded, processed, summarized, and reported within the time period specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

Our management evaluated, with the participation of our principal executive officer and principal financial officer (our “Certifying Officers”), the effectiveness of our disclosure controls and procedures as of June 30, 2026, pursuant to Rule 13a-15(b) under the Exchange Act. Based upon that evaluation, our Certifying Officers concluded that, as of June 30, 2026, our internal controls over financial reporting were not effective due to the material weaknesses in internal control over financial reporting described below. As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025, we identified material weaknesses in our internal control over financial reporting. As of June 30, 2026, these material weaknesses have not been remediated.

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Management’s Report on Internal Controls Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-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 condensed consolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or because the degree of compliance with policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our Certifying Officers, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of June 30, 2026, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Based on that evaluation, our Certifying Officers have concluded that, as of June 30, 2026, our internal controls over financial reporting were not effective due to the material weaknesses in internal control over financial reporting described below:

Changes in Internal Controls over Financial Reporting

There have been no changes in our internal controls over financial reporting that occurred during the six months ended June 30, 2026, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting, other than as described above.
