Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted 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 in our reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

As required by Rules 13a-15 and 15d-15 under the Exchange Act, our management carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures under the supervision of our Chief Executive Officer and our Chief Financial Officer and concluded that our disclosure controls and procedures were not effective as of March 31, 2026. Material weaknesses relating to the Design and Implementation of Control Activities and Monitoring Activities were identified. The Company did not have sufficient resources with the relevant expertise to perform an effective risk assessment process, design and implement controls supported by documentation and provide evidence that such controls designed was based on the COSO Framework.

The material weaknesses in risk assessment, control activities and monitoring activities contributed to the following material weaknesses: (i) the Company did not complete a documented risk assessment, and (ii) the Company did not identify all risks and design relevant controls related to system of internal controls. As a consequence of the aggregation of the foregoing deficiencies in the Company’s DC&P and ICFR design, the Company did not have effective control activities related to the design of process-level and management review control activities. Aside from these deficiencies, management believes that the Company’s condensed consolidated financial statements for three months ended March 31, 2026, present fairly in all material respects, the Company’s financial position, results of operations, changes in shareholders’ equity and cash flows in accordance with U.S. GAAP. The Company does not believe and is not aware of any circumstance in which the potential weaknesses have impacted the Company’s financial reporting and as a result, there were no material adjustments to the Company’s condensed consolidated financial statements for the three months ended March 31, 2026. In addition, there were no changes to previously released financial results. However, if the collective deficiencies were deemed to create a material weakness, a material misstatement to our consolidated financial statements might not be prevented or detected on a timely basis.

Management’s Remediation Measures

To address the deficiencies identified, management, with oversight of the Audit Committee, has implemented, or will implement, remediation measures to further address the deficiencies in the design of its DC&P and ICFR. The Company intends to complete such remedial measures by December 31, 2027, and is currently underway with planning and scoping procedures. Management has also performed an initial risk assessment using a top-down, risk-based approach with respect to the risks of material misstatement of the consolidated financial statements. In addition, compensating controls have been applied to a number of areas where the risks of material misstatement are considered moderate to high. The Company is engaging outside resources to strengthen the business process documentation and help with management’s self-assessment and testing of internal controls. Although the Company can give no assurance that these actions will remediate these deficiencies or that additional deficiencies or a material weaknesses will not be identified in the future, management believes the foregoing efforts will, when implemented, strengthen our DC&P and ICFR. Management will take additional remedial actions as necessary as they continue to evaluate and work to improve the Company’s control environment.

Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the three months ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
