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 for 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 June 30, 2026, our disclosure controls and procedures were not effective as of such date due to a material weakness in internal control over financial reporting, as described below.

Material Weakness 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 2025 Form 10-K, management identified a material weakness in our internal controls over financial reporting. The Company did not maintain sufficient accounting and finance personnel with the appropriate level of experience and technical expertise to consistently execute and maintain effective internal controls over financial reporting, including controls related to:

•The preparation and review of complex accounting estimates and judgments,

•The timely performance of management review controls, and

•The execution of controls designed to ensure the completeness and accuracy of account reconciliations and financial statement disclosures.

While management has designed appropriate internal controls to address the risks of material misstatement in these areas, the Company lacked adequate personnel resources during the period to execute these controls at a level of precision and consistency necessary to prevent or detect material misstatements on a timely basis.

Based on the results of its evaluation and the material weakness 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 June 30, 2026.

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, other than the remediation activities noted below.

Remediation of Material Weakness

Management is committed to remediating the identified material weakness and continues the implementation of the following measures:

•Hiring additional accounting and finance personnel with relevant public company reporting and technical accounting experience;

•Expanding the use of third-party technical accounting and financial reporting advisors to supplement internal resources during peak reporting periods; and

•Enhancing documentation and execution standards for key management review controls.

Management believes these actions, when fully implemented and operating effectively, will remediate the material weakness. However, the material weakness cannot be considered remediated until the applicable controls have operated for a sufficient period of time and management has concluded, through testing, that the controls are operating effectively.

Unless and until the material weakness is remediated, or if new material weaknesses arise in the future, material misstatements could occur and go undetected in our interim Condensed Consolidated Financial Statements 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 weakness 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.
