Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act as of March 31, 2025. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of March 31, 2025 due to the material weaknesses in our internal control over financial reporting as previously identified in our 2024 Annual Report that were not remediated as of March 31, 2025.

In light of this fact, our management has performed additional analyses, reconciliations, and other post-closing procedures and has concluded that, notwithstanding the material weaknesses in our internal control over financial reporting, the unaudited 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, our financial condition, results of operations and cash flows for the periods presented in conformity with GAAP.

Remediation of Material Weaknesses

We continue to implement our remediation plans that address the material weaknesses in our internal controls over financial reporting as previously discussed in Part II, Item 9A of our 2024 Annual Report. The remaining remediation work involves (i) assessing the risk of fraud with respect to financial reporting, and combining this with our other risk assessment processes; (ii) designing and implementing enhanced business processes and controls and ensuring these operate effectively; and (iii) enhancing our IT processes and controls across the remaining applications for which deficiencies have been identified, particularly in relation to the general IT controls around user access management and change management where operating effectiveness needs to be demonstrated over a sustained period. The implementation of our remediation measures will require validation and testing of the design and operating effectiveness of internal controls over a sustained period. We will not consider the material weaknesses remediated until our enhanced controls are operational for a sufficient period of time and tested, enabling management to conclude that the enhanced controls are operating effectively. In addition, we cannot ensure that the measures taken by us to date, and actions that we may take in the future, will be sufficient to remediate these deficiencies or that they will prevent or avoid potential future deficiencies.

Changes in Internal Control over Financial Reporting

We are taking actions to remediate the material weaknesses relating to our internal control over financial reporting, as described above. Except as otherwise described herein, there were no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
