Disclosure Controls and Procedures

Our management has established and maintains disclosure controls and procedures that are designed to ensure that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to management, including our CEO and Chief Financial Officer ("CFO"), as appropriate, to allow timely decisions regarding required disclosure. Management carried out an evaluation, under the supervision and with the participation of our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our CEO and CFO have concluded that as of June 30, 2025, the Company's disclosure controls and procedures were effective.

Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the three month period ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

We are currently undertaking a significant multi-year global ERP implementation to upgrade our information technology platforms and business processes. The implementation is occurring in phases over several years, which began in 2023. During 2023, we implemented the human capital resources management module, including the payroll application for all locations within the United States, the ERP at Corporate and one manufacturing site and the consolidations and reporting module. During 2024, we implemented the ERP at two additional manufacturing sites.

As a result of this multi-year implementation, we expect certain changes to our processes and procedures, which, in turn, will result in changes to our internal control over financial reporting. While we expect this implementation to strengthen our internal control over financial reporting by automating certain manual processes and standardizing business processes and reporting across our organization, we will continue to evaluate and monitor our internal control over financial reporting as processes and procedures in the affected areas evolve.
