Workhorse Group Inc.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the specified time periods and accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q was made under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer.

Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of September 30, 2025, our disclosure controls and procedures were not effective as of such date due to material weaknesses in internal control over financial reporting, as described below.

Material Weaknesses in Internal Control over Financial Reporting

There are inherent limitations on the effectiveness of any system of internal controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective internal controls and procedures can only provide reasonable assurance of achieving their control objectives.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

As disclosed in our 2024 Form 10-K, management identified material weaknesses in our internal controls over financial reporting. During the audit process related to the year ended December 31, 2023, management identified a material weakness in the design of the Company’s internal controls related to our review of third-party valuation deliverables regarding our convertible debt and warrant liability. Additionally, during the third quarter of 2024, management identified a material weakness related to our failure to timely issue finalized quarterly reports for two consecutive quarters due to the turnover of key accounting positions within the Company’s finance organization and the ability of Company accounting personnel who had recently assumed new and additional responsibilities, with the assistance of external accounting consultants, to identify, evaluate and address technical accounting and disclosure issues that affect our Consolidated Financial Statements on a timely basis. As a result of the Company’s previously disclosed efforts to reduce costs and preserve liquidity, the Company was not able to attract, develop and retain sufficient resources to implement internal control responsibilities, resulting in the lack of a sufficient complement of personnel with an appropriate degree of knowledge and experience. Management has determined that these material weaknesses are related to employee turnover and insufficient internal resources in technical accounting and financial reporting impacting our internal control over financial reporting in the third quarter of 2024 and did not affect previously reported periods.

Based on the results of its evaluation and the material weaknesses described above, management concluded that the Company’s internal control over financial reporting was not effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with GAAP as of September 30, 2025.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Remediation of Material Weaknesses

Due to the control weaknesses outlined above, management has implemented additional measures to review the key inputs and assumptions used by third-party valuation subject matter specialists. These enhancements aim to address deficiencies in the fair value calculation of the convertible note and warrant liability. We are also in the process of designing and implementing a robust plan intended to address the personnel-related material weakness identified in 2024. These remediation measures will be focused on ensuring that we have a sufficient number of accounting personnel, including the use of third-party resources, and that such personnel have appropriate training and experience with our disclosure and financial reporting process.

The remediation plans are actively underway, and management will continue to assess its effectiveness. Until the identified material weaknesses are fully remediated and operating effectively for a sustained period, management will continue to assess and enhance internal controls. We are committed to ensuring that these deficiencies are fully addressed and will provide updates on our progress in future filings.

While management has taken steps to remediate these control weaknesses, the material weaknesses are still unresolved. Consequently, our internal control over financial reporting was not effective as of September 30, 2025.

Unless and until these material weaknesses are remediated, or if new material weaknesses arise in the future, material misstatements could occur and go undetected in our interim or annual Consolidated Financial Statements, and we may be required to restate our financial statements. In addition, we may experience delays in satisfying our reporting obligations or to comply with Securities and Exchange Commission rules and regulations, which could result in, among other things, regulatory or enforcement actions, securities litigation, limitations on our ability to access capital markets, debt rating agency downgrades or rating withdrawals, or loss in confidence of our investors, any one of which could adversely affect the valuation of our Common Stock and our business prospects. We can give no assurance that the measures we have taken and plan to take in the future will remediate the material weaknesses identified or that any additional material weaknesses will not arise in the future due to a failure to implement and maintain adequate internal control over financial reporting.
