Microvast Holdings, Inc.

Evaluation of Disclosure Controls and Procedures

Under supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we 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 June 30, 2025. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective as of June 30, 2025, as a result of the material weaknesses in the Company's internal controls over financial reporting identified below. As defined in the standards established by the Public Company Accounting Oversight Board, a “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

In light of these material weaknesses, we performed additional procedures and analysis to ensure that the financial statements included in this Report were prepared in accordance with U.S. GAAP. Based on these procedures, management, including our Chief Executive Officer and Chief Financial Officer, believes the unaudited condensed consolidated financial statements included in this Report fairly represent in all material respects our financial condition, results of operations and cash flows at and for the periods presented, in accordance with U.S. GAAP.

Material Weakness in Internal Controls

As previously disclosed in Part II, Item 9A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, in connection with the audit of the financial year ended December 31, 2024, we identified control deficiencies in the design and operation of internal controls over financial reporting that constituted a material weakness in aggregation. Significant improvement in the design and monitoring of information technology general controls (“GITC”) was made in 2024, however a material weakness has been identified relating to the design, implementation and monitoring of GITC for the ERP system that are relevant to the preparation of our financial statements. In particular, the Company’s GITC findings included: (i) inappropriate implementation of controls allowed developers to gain access to application layer of ERP; (ii) the monitoring controls were not appropriately designed to review the overall operations of the privileged users; and (iii) the monitoring controls were not appropriately designed to review the permissions granted to users. A substantial portion of the Company's controls are dependent upon the information derived from the ERP system and therefore the dependent controls were also concluded to be ineffective.

Material Weakness Remediation

Subsequent to the identification of the material weakness, we have taken steps to address the control deficiencies and continue to implement our remediation plan, which we believe addresses the underlying causes. We executed on our remediation plan for the material weakness by:

•Removing all inappropriate access as of December 31, 2024, and strictly following segregation of duty rule set for developers.

•Establishing more robust and precise processes to monitor the privileged user activities.

•Establishing more robust and precise processes for the user access review.

While we believe these efforts will continue to improve our internal controls and address the underlying causes of the material weakness, the material weakness will not be remediated until our remediation plan has been fully implemented and tested and we have concluded that following the improvements, our IT general controls are operating effectively for a sufficient period of time.

Changes in Internal Control Over Financial Reporting

As described above, the Company is taking steps to remediate the material weakness noted above. Other than the changes in connection with these remediation steps, there have been no changes in our internal control over financial reporting during the quarter ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, believe that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable levels of assurance of achieving their objectives and are effective at the reasonable assurance level. However, management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors or all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. The design of any system of controls also is based in part upon 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. Over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.
