Evaluation of Disclosure Controls and Procedures and Changes in Internal Control over Financial Reporting

We maintain a set of disclosure controls and procedures designed to ensure that material information required to be disclosed in our filings under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that material information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosures. Our CEO and CFO have evaluated these disclosure controls and procedures as of the end of the period covered by this quarterly report on Form 10-Q and have determined that such disclosure controls and procedures were effective.

During the six-month period ended June 30, 2026, the Company migrated certain of our business applications and financial processing systems to a newly implemented Enterprise Resource Planning (“ERP”) system. The migration and implementation impacted operational processes, as well as certain accounting and financial reporting processes. In connection with the migration and ERP implementation, we have updated and will continue to update our internal control over financial reporting, as necessary, to accommodate modifications to our business processes and accounting procedures. During the six-month period ended June 30, 2026, the migration and ERP implementation resulted in changes that materially affected our internal control over financial reporting. These system migrations and implementations did not have an adverse effect, nor do we expect will have an adverse effect, on our internal control over financial reporting.

Except with respect to the implementation of the ERP, there have been no changes in our internal control over financial reporting during the six-month period ended June 30, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We will continue to assess the impact on our internal control over financial reporting as we continue to further refine and enhance the new ERP and other business applications.
