Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this report. Such disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosures.

Based on this evaluation, our CEO and CFO have concluded that our disclosure controls and procedures were not effective as of September 30, 2026 because of the material weakness in our internal control over financial reporting identified in connection with the audit of our consolidated financial statements for the year ended December 31, 2025, as described below, which continues to exist as of September 30, 2026.

Notwithstanding the material weakness described below, management believes the condensed consolidated financial statements for the periods covered by and included in this Quarterly Report on Form 10-Q fairly present, in all material respects, the Company’s financial condition, results of operations, and cash flows for the periods presented in accordance with generally accepted accounting principles in the United States.

As previously reported in our Annual Report on Form 10-K for the year ended December 31, 2025, we identified the following material weakness in internal control over financial reporting related to information technology general controls (“ITGCs”) as of December 31, 2025:

We did not design and maintain effective ITGCs for information systems that are relevant to the preparation of our consolidated financial statements. Specifically, we did not design and maintain: (i) program change management controls to ensure that program and data changes are identified, tested, authorized, and implemented appropriately; and (ii) user access controls to ensure appropriate segregation of duties and to adequately restrict user and privileged access to appropriate personnel. These IT deficiencies did not result in a material misstatement to the consolidated financial statements, however, the deficiencies, when aggregated, could impact maintaining effective segregation of duties, as well as the effectiveness of IT-dependent controls (such as automated controls that address the risk of material misstatement to one or more assertions, along with the IT controls and underlying data that support the effectiveness of system-generated data and reports) that could result in misstatements potentially impacting all financial statement accounts and disclosures that would not be prevented or detected. Accordingly, management has determined these deficiencies constitute a material weakness.

Remediation of Material Weakness - Plan and Progress

Management remains committed to maintaining a strong internal control environment and has made progress in remediating the material weakness described above. During 2026, management has taken the following actions:

•hired additional IT Compliance and Oversight personnel in 2026 with responsibility for the design, implementation, and ongoing monitoring of ITGCs;

•designed and implemented enhanced program change management and user access controls; and

•developed and delivered ITGC training to information technology and business system owners in March and September 2026, with a focus on access management controls.

Management has begun testing the design and operating effectiveness of these controls, and the results of our testing to date indicate that the Company's control environment has improved since the material weakness was identified. While we have made progress, the material weakness will not be considered remediated until the relevant controls have operated effectively for a sufficient period of time to prevent or detect a material misstatement. While management believes the actions described above will remediate the material weakness, the exact timing of completion cannot be determined.

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, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.
