Evaluation of 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 the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness 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 Chief Executive Officer and Chief Financial Officer have concluded that as of December 31, 2024, the Company's disclosure controls and procedures were effective.

Management's Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f) under the Exchange Act). The Company's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, management carried out an evaluation of the effectiveness of the Company's internal control over financial reporting as of December 31, 2024, based on the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). Based on that evaluation, management concluded that the Company's internal control over financial reporting was effective as of December 31, 2024.

The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is set forth in Part II, Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

We are currently undertaking a significant multi-year 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 the second quarter of 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.

With the exception of the implementations described above, 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 December 31, 2024 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
